IDT8V89317
IDT8V89317 is 10G Ethernet PLL and IEEE 1588 Synthesizer manufactured by IDT.
Features
HIGHLIGHTS
- Digital PLL locks to GPS or Ethernet physical layer clocks
- Provides clocks for 1 Gigabit and 10 Gigabit Ethernet, QSGMII and
XAUI
- Internal Digitally Controlled Oscillator supports IEEE 1588 clocks generation
- Jitter generation <0.3ps RMS (10 k Hz to 20 MHz), meets jitter requirements of leading PHYs supporting 10GBASE-R, QSGMII and XAUI
MAIN Features
- Digital PLL synchronizes with GPS or Ethernet connected synchronization sources
- DPLL bandwidth is selectable to be 15 m Hz or 1.2 Hz
- DPLL holdover accuracy is 1.1X10-5 ppm and instantaneous hold- over accuracy is 4.4X10-8 ppm
- Input references are monitored for frequency offset and activity
- DPLL holdover, free run and hitless reference switching can be forced by the host processor or can be automatically controlled by an internal state machine
- Internal DCO has resolution of 0.01105...
