Overview

The IDT8V89316 is used to frequency synchronize equipment with an Ethernet connected 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 IDT8V89316 low jitter output clocks can be used to directly time Gigabit Ethernet PHYs and QSGMII devices.

8V89316 Functional Diagram
  • Digital PLL synchronizes with Ethernet connected synchronization sources
  • DPLL bandwidth is 1.2 Hz; DPLL holdover accuracy is 1.1X10-5 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 ppb and can be controlled by an external processor via I2C interface for IEEE 1588 clock generation
  • One Analog PLL for jitter attenuation
  • Jitter generation <0.65ps RMS (10 kHz to 20 MHz), meets jitter requirements of 1 GbE PHYs and QSGMII
  • IN1, IN2 and IN3 accept single ended reference clocks whose frequencies can be 25 MHz, 125 MHz or 156.25 MHz
  • OUT1 outputs a differential clock with frequency of 125 MHz or 156.25 MHz
  • OUT2 to OUT6 output differential clocks all with the same frequency of 125 MHz or 156.25 MHz
  • OUT7 outputs a free-running LVCMOS clock with frequency of 25 MHz
