It consists of a low-noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider and programmable N divider. The 14-bit reference counter (R counter), allows selectable REFIN frequencies at the PFD input.A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). In addition, by programming R and N to 1, the device can be used as a standalone PFD and charge pump.The ADF4002-EP supports defense and aerospace applications (AQEC standard).

The ADG1211 / ADG1212 / ADG1213 are monolithic complementary metal-oxide semiconductor (CMOS) devices containing four independently selectable switches designed on an iCMOS® (industrial CMOS) process. iCMOS is a modular manufacturing process combining high voltage CMOS and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no previous generation of high voltage devices has been able to achieve. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.The ultralow capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. Fast switching speed coupled with high signal bandwidth make the devices suitable for video signal switching.iCMOS construction ensures ultralow power dissipation, making the devices ideally suited for portable and battery-powered instruments.The ADG1211 / ADG1212 / ADG1213 contain four independent single-pole/single-throw (SPST) switches. The ADG1211 and ADG1212 differ only in that the digital control logic is inverted. The ADG1211 switches are turned on with Logic 0 on the appropriate control input, while Logic 1 is required for the ADG1212. The ADG1213 has two switches with digital control logic similar to that of the ADG1211; the logic is inverted on the other two switches.

The ADG2188 is an analog cross point switch with an array size of 8 × 8. The switch array is arranged so that there are eight columns by eight rows, for a total of 64 switch channels. The array is bidirectional, and the rows and columns can be configured as either inputs or outputs. Each of the 64 switches can be addressed and configured through the I2C-compatible interface. Standard, full speed, and high speed (3.4 MHz) I2C interfaces are supported. Any simultaneous switch combination is allowed. An additional feature of the ADG2188 is that switches can be updated simultaneously, using the LDSW command. In addition, a RESET option allows all of the switch channels to be reset/off.

The ADG408 is a monolithic CMOS analog multiplexer comprising 8 single channels. The ADG408 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and A2. An EN input is used to enable or disable the device. When disabled, all channels are switched OFF. The ADG408 is designed on an enhanced LC2MOS process which provides low power dissipation yet gives high switching speed and low on resistance. Each channel conducts equally well in both directions when ON and has an input signal range which extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All channels exhibit break before make switching action preventing momentary shorting when switching channels. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
