10G Ethernet PLL and IEEE 1588 Synthesizer

The IDT8V89317 is used to frequency synchronize equipment with an Ethernet connected reference or with a GPS based 1PPS reference; its integrated DCO (Digitally Controlled Oscillator) can be controlled by an external IEEE 1588 clock recovery servo to synthesize IEEE 1588-based clocks. The IDT8V89317 ultra-low jitter output clocks can be used to directly time 10 Gigabit Ethernet PHYs and QSGMII devices.
