The AD9548 provides synchronization for many systems, including synchronous optical networks (SONET/SDH). The AD9548 generates an output clock synchronized to one of up to four differential or eight single-ended external input references. The digital PLL allows for reduction of input time jitter or phase noise associated with the external references. The AD9548 continuously generates a clean (low jitter), valid output clock even when all references have failed by means of a digitally controlled loop and holdover circuitry.
The AD9548 operates over an industrial temperature range of −40°C to +85°C.

Analog Devices AD7328BRUZ
The AD7328BRUZ is a 8-channel Software-selectable True Bipolar Input 12-bit Plus Sign ADC designed on the iCMOS™ (industrial CMOS) process. iCMOS is a process combining high voltage silicon with submicron CMOS and complementary bipolar technologies. It enables the development of a wide range of high performance analogue ICs capable of 33V operation in a footprint that no previous generation of high voltage parts could achieve. Unlike analogue ICs using conventional CMOS processes, iCMOS components can accept bipolar input signals while providing increased performance, dramatically reduced power consumption and reduced package size. It can accept true bipolar analogue input signals. The successive approximation ADC has four software-selectable input ranges: ±10, ±5, ±2.V and 0 to +10V. Each analogue input channel can be independently programmed to one of the four input ranges.
- 12-bit Plus sign SAR ADC
- True bipolar input ranges
- 1MSPS throughput rate
- 8 Analogue input channels with channel sequencer
- Single-ended, true differential and pseudo differential analogue input capability
- High analogue input impedance
- Low power
- Temperature indicator
- 22MHz Full power signal bandwidth

Texas Instruments TLC5540IPW
The TLC5540 is a high-speed, 8-bit analog-to-digital converter (ADC) that converts at sampling rates up to 40 megasamples per second (MSPS). Using a semiflash architecture and CMOS process, the TLC5540 is able to convert at high speeds while still maintaining low power consumption and cost. The analog input bandwidth of 75 MHz (typ) makes this device an excellent choice for undersampling applications. Internal resistors are provided to generate 2-V full-scale reference voltages from a 5-V supply, thereby reducing external components.
The digital outputs can be placed in a high impedance mode. The TLC5540 requires only a single 5-V supply for operation.
