Echotek Series ECSG-1RHSCT Low Phase Noise AD Clock Generator

Product Description

The EchotekTM Series ECSG-1RHSCT low phase noise A/D clock generators are one-reference high-speed clock transmitters for distribution to board-level, mixed signal products such as analog-to-digital converters (ADC), digital-to-analog converters (DAC), digital receivers, and digital upconverters. The VME version has five high-speed clock output connectors; the PMC version has two. The clock source is generated using an ADF4113 RF PLL frequency synthesizer driving a voltage-controlled oscillator (VCO). VCOs are available in variable ranges.
