The ADE7953 is a high accuracy electrical energy measurementIC intended for single phase applications. It measures line voltageand current and calculates active, reactive, and apparent energy,as well as instantaneous rms voltage and current.The device incorporates three Σ-Δ ADCs with a high accuracyenergy measurement core. The second input channel simultaneouslymeasures neutral current and enables tamper detectionand neutral current billing. The additional channel incorporatesa complete signal path that allows a full range of measurements.Each input channel supports independent and flexible gain stages,making the device suitable for use with a variety of current sensorssuch as current transformers (CTs) and low value shunt resistors.Two on-chip integrators facilitate the use of Rogowski coil sensors.The ADE7953 provides access to on-chip meter registers via avariety of communication interfaces including SPI, I2C, and UART.Two configurable low jitter pulse output pins provide outputs thatare proportional to active, reactive, or apparent energy, as well ascurrent and voltage rms. A full range of power quality informationsuch as overcurrent, overvoltage, peak, and sag detection areaccessible via the external IRQ pin. Independent active, reactive,and apparent no-load detections are included to prevent “metercreep.” Dedicated reverse power (REVP), zero-crossing voltage(ZX), and zero-crossing current (ZX_I) pins are also provided. TheADE7953 energy metering IC operates from a 3.3 V supply voltageand is available in a 28-lead LFCSP package.

The ADF4158 is a 6.1 GHz, fractional-N frequency synthesizer with modulation and waveform generation capability. It contains a 25-bit fixed modulus, allowing subhertz resolution at 6.1 GHz. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. There is a sigma-delta (Σ-Δ) based fractional interpolator to allow programmable fractional-N division. The INT and FRAC registers define an overall N-divider as N = INT + (FRAC/225).The ADF4158 can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation. There are also a number of frequency sweep modes available, which generate various waveforms in the frequency domain, for example, sawtooth and triangular waveforms. Sweeps can be set to run automatically, or each step manually triggered by an external pulse. The ADF4158 features cycle slip reduction circuitry, which leads to faster lock times, without the need for modifications to the loop filter.Control of all on-chip registers is via a simple 3-wire interface. The device operates with a power supply ranging from 2.7 V to 3.3 V and can be powered down when not in use.Applications Frequency modulated continuous wave (FMCW) radar Communications test equipment

The ADF7023 is a very low power, high performance, highly integrated 2FSK/GFSK/OOK/MSK/GMSK transceiver designed for operation in the 862 MHz to 928 MHz and 431 MHz to 464 MHz frequency bands, which cover the worldwide license-free ISM bands at 433 MHz, 868 MHz, and 915 MHz. It is suitable for circuit applications that operate under the European ETSI EN300-220, the North American FCC (Part 15), the Chinese short-range wireless regulatory standards, or other similar regional standards. Data rates from 1 kbps to 300 kbps are supported.The transmit RF synthesizer contains a VCO and a low noise fractional-N PLL with an output channel frequency resolution of 400 Hz. The VCO operates at 2× or 4×, 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 allows 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 ±2 MHz offset and 74 dB at ±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, automatic frequency control (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 through a program download. 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 Wireless MBUS Home automation Process and building control Wireless sensor networks (WSNs) Wireless healthcare
