The AD9911 is a complete direct digital synthesizer (DDS).This device includes a high speed DAC with excellent widebandand narrowband spurious-free dynamic range (SFDR) as well asthree auxiliary DDS cores without assigned digital-to-analogconverters (DACs). These auxiliary channels are used for spurreduction, multitone generation, or test-tone modulation.The AD9911 is the first DDS to incorporate SpurKillertechnology and multitone generation capability. Multitonemode enables the generation up to four concurrent carriers;frequency, phase and amplitude can be independentlyprogrammed. Multitone generation can be used for systemtests, such as inter-modulation distortion and receiver blockersensitivity. SpurKilling enables customers to improve SFDRperformance by reducing the magnitude of harmoniccomponents and/or the aliases of those harmonic components.Test-tone modulation efficiently enables sine wave modulationof amplitude on the output signal using one of the auxiliaryDDS cores.The AD9911 can perform modulation of frequency, phase, oramplitude (FSK, PSK, ASK). Modulation is implemented bystoring profiles in the register bank and applying data to theprofile pins. In addition, the AD9911 supports linear sweep offrequency, phase, or amplitude for applications such as radarand instrumentation.The DDS acts as a high resolution frequency divider with theREF_CLK as the input and the DAC providing the output. TheREF_CLK input can be driven directly or used in combinationwith an integrated REF_CLK multiplier (PLL). The REF_CLKinput also features an oscillator circuit to support an externalcrystal as the REF_CLK source. The crystal can be used incombination with the REF_CLK multiplier.The AD9911 I/O port offers multiple configurations to providesignificant flexibility. The I/O port offers an SPI-compatiblemode of operation that is virtually identical to the SPI operationfound in earlier Analog Devices DDS products.Flexibility is provided by four data pins (Pin SDIO_0,Pin SDIO_1, Pin SDIO_2, and Pin SDIO_3) that allow fourprogrammable modes of I/O operation.The DAC output is supply referenced and must be terminatedinto AVDD by a resistor and an AVDD center-tapped transformer.The DAC has its own programmable reference to enabledifferent full-scale currents.The DDS core (the AVDD pins and the DVDD pins) is poweredby a 1.8 V supply. The digital I/O interface (SPI) operates at3.3 V and requires that the Pin DVDD_I/O (Pin 49) beconnected to 3.3 V.

The ADF4212L is a dual frequency synthesizer that can be usedto implement local oscillators (LO) in the up-conversion and down-conversion sections of wireless receivers and transmitters. It can provide the LO for both the RF and IF sections. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, programmable A and B counters, and a dual modulus prescaler (P/P + 1). The A (6-bit) and B (12-bit) counters, in conjunction with the dual modulus prescaler (P/P + 1), implement an Ndivider (N = BP + A). In addition, the 15-bit reference counter(R Counter), allows selectable REFIN frequencies at the PFDinput. A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with external loop filters and voltage controlled oscillators (VCOs).Control of all the on-chip registers is via a simple 3-wire interface with 1.8 V compatibility.

The ADG3308 is a bidirectional level translator containing eight bidirectional channels. The ADG3308 can be used in multivoltage digital system applications, such as a data transfer between a low voltage DSP controller and a higher voltage device. The internal architecture allows the device to perform bidirectional level translation without an additional signal to set the direction in which the translation takes place.The voltage applied to VCCA sets the logic levels on the A side of the device, and VCCY sets the levels on the Y side. For proper operation, VCCA must always be less than VCCY. The VCCA compatible logic signals applied to the A side of the device appear as VCCY compatible levels on the Y side. Similarly, VCCY compatible logic levels applied to the Y side of the device appear as VCCA compatible logic levels on the A side.The enable pin (EN) provides three-state operation on both the A side and the Y side pins. When the EN pin is pulled low, the terminals on both sides of the device are in the high impedance state. For normal operation, EN should be driven high.The ADG3308 is available in a compact 20-lead TSSOP and a 20-lead LFCSP. The EN pin is referred to the VCCY supply voltage.
