The ADF7021-V is a high performance, low power, narrow-band RF transceiver based on the ADF7021-N. The architecture of the ADF7021-V transceiver is similar to that of the ADF7021-N except that an external VCO is used by the on-chip RF synthesizer for applications that require improved phase noise performance.The ADF7021-V is designed to operate in both the license-free ISM bands and in the licensed bands from 80 MHz to 960 MHz.To minimize RF feedthrough and spurious emissions, the external VCO operates at 2? or 4? the desired RF frequency; the ADF7021-V supports a maximum VCO frequency operation of 1920 MHz. The 4? VCO operation is programmable by enabling an additional on-chip divide-by-2 outside the RF synthesizer loop and offers improved phase noise performance.As with the ADF7021-N receiver, the IF filter bandwidths of 9 kHz, 13.5 kHz, and 18.5 kHz are supported, making the ADF7021-V ideally suited to worldwide narrow-band telemetry applications.The part has both Gaussian and raised cosine transmit data filtering options to improve spectral efficiency for narrow-band applications.

The ADF7023-J is a very low power, high performance, highly integrated 2FSK/GFSK/MSK/GMSK transceiver designed for operation in the 902 MHz to 958 MHz frequency band, which covers the ARIB Standard T96 band at 950 MHz. Data rates from 1 kbps to 300 kbps are supported.The transmit RF synthesizer contains a VCO and a low noise fractional-N phase locked loop (PLL) with an output channel frequency resolution of 400 Hz. The VCO operates at twice the fundamental frequency to reduce spurious emissions. The receive and transmit synthesizer bandwidths are automatically, and independently, configured to achieve optimum phase noise, modulation quality, and settling time. The transmitter output power is programmable from ?20 dBm to +13.5 dBm, with automatic PA ramping to meet transient spurious specifications. The part possesses both single-ended and differential PAs, which allow for Tx antenna diversity.The receiver is exceptionally linear, achieving an IP3 specification of ?12.2 dBm and ?11.5 dBm at maximum gain and minimum gain, respectively, and an IP2 specification of 18.5 dBm and 27 dBm at maximum gain and minimum gain, respectively. The receiver achieves an interference blocking specification of 66 dB at a ?2 MHz offset and 74 dB at a ?10 MHz offset. Thus, the part is extremely resilient to the presence of interferers in spectrally noisy environments. The receiver features a novel, high speed, AFC loop, allowing the PLL to find and correct any RF frequency errors in the recovered packet. A patent pending image rejection calibration scheme is available by downloading the image rejection calibration firmware module to program RAM. The algorithm does not require the use of an external RF source nor does it require any user intervention once initiated. The results of the calibration can be stored in nonvolatile memory for use on subsequent power-ups of the transceiver.See data sheet for additional information.Applications Smart metering IEEE 802.15.4g Home automation Process and building control Home Energy Management Systems (HEMS) Wireless sensor networks (WSNs) Wireless healthcare

With its support of GFSK/FSK/GMSK/MSK modulation schemes, the IC can operate over a wide range of data rates from 50 kbps to 2 Mbps and is, therefore, equally suitable for proprietary applications in the areas of smart metering, industrial control, home and building automation, and consumer electronics. In addition, the agile frequency synthesizer of the ADF7242, together with short turnaround times, facilitates the implementation of FHSS systems.The transmitter path of the ADF7242 is based on a direct closed-loop VCO modulation scheme using a low noise fractional-N RF frequency synthesizer. The automatically calibrated VCO operates at twice the fundamental frequency to reduce spurious emissions and avoid PA pulling effects. The bandwidth of the RF frequency synthesizer is automatically optimized for transmit and receive operations to achieve optimum phase noise, modulation quality, and synthesizer settling time performance. The transmitter output power is programmable from ?20 dBm to +4 dBm with automatic PA ramping to meet transient spurious specifications. An integrated biasing and control circuit is available in the IC to significantly simplify the interface to external PAs.The receive path is based on a zero-IF architecture enabling very high blocking resilience and selectivity performance, which are critical performance metrics in interference dominated environments such as the 2.4 GHz band. In addition, the architecture does not suffer from any degradation of blocker rejection in the image channel, which is typically found in low IF receivers. In GFSK/FSK modes, the receiver features a high speed automatic frequency control (AFC) loop, which allows the frequency synthesizer to find and correct any frequency errors in the received packet.The IC can operate with a supply voltage between 1.8 V and 3.6 V with very low power consumption in receive and transmit modes while maintaining its excellent RF performance, making it especially suitable for battery-powered systems.The ADF7242 features a flexible dual-port RF interface that can be used with an external LNA and/or PA in addition to supporting switched antenna diversity.The ADF7242 incorporates a very low power custom 8-bit processor that supports a number of transceiver management functions. These functions are handled by the two main modules of the processor; the radio controller and the packet manager.See data sheet for additional information.APPLICATIONS Wireless sensor networks Automatic meter reading/Smart metering Industrial wireless control Healthcare Wireless audio/video Consumer electronics Zigbee

The ADM1060?is a programmable supervisory/sequencing device that offers a single chip solution for multiple power supply fault detection and sequencing in communications systems.In central offices, servers, and other infrastructure systems, a common backplane dc supply is reduced to multiple board supplies using dc-to-dc converters. These multiple supplies are used to power different sections of the board, such as 3.3 V logic circuits, 5 V logic circuits, DSP core, and DSP I/O circuits. There is usually a requirement that certain sections power up before others; for example, a DSP core may need to power up before the DSP I/O, or vice versa, to avoid damage, miscommunication, or latch-up. The ADM1060 facilitates this, providing supply fault detection and sequencing/combinatorial logic for up to seven independent supplies. The seven supply fault detectors consist of one high voltage detector (up to +14.4 V), two bipolar voltage detectors (up to +6 V or down to ?6 V), and four positive low voltage detectors (up to +6 V). All of the detectors can be programmed to detect undervoltage, overvoltage, or out-ofwindow (undervoltage or overvoltage) conditions. The inputs to these supply fault detectors are via the VH (high voltage) pin, VBn (positive or negative) pins, and VPn (positive only) pins. Either the VH supply or one of the VPn supplies is used to power the ADM1060 (whichever is highest). This ensures that in the event of a supply failure, the ADM1060 is kept alive for as long as possible, thus enabling a reliable fault flag to be asserted and the system to be powered down in an ordered fashion.Other inputs to the ADM1060 include a watchdog detector (WDI) and four general-purpose inputs (GPIn). The watchdog detector can be used to monitor a processor clock. If the clock does not toggle (transition from low to high or from high to low) within a programmable timeout period (up to 18 sec.), a fail flag will assert. The four general-purpose inputs can be configured as logic buffers or to detect positive/negative edges and to generate a logic pulse or level from those edges. Thus, the user can input control signals from other parts of the system (e.g., RESET or POWER_GOOD) to gate the sequencing of the supplies supervised by the ADM1060.The ADM1060 features nine programmable driver outputs (PDOs). All nine outputs can be configured to be logic outputs, which can provide multiple functions for the end user such as RESET generation, POWER_GOOD status, enabling of LDOs, and watchdog timeout assertion. PDOs 1 to 4 have the added feature of being able to provide an internally charge-pumped high voltage for use as the gate drive of an external N-channel FET that could be placed in the path of one of the supplies being supervised.APPLICATIONS Central office systems Servers Infrastructure network boards High density, multivoltage system cards
