IDT8V89316
IDT8V89316 is Ethernet PLL and IEEE 1588 Synthesizer manufactured by IDT.
Features
HIGHLIGHTS
- Digital PLL locks to Ethernet physical layer clocks
- Provides clocks for 1 Gigabit Ethernet and QSGMII
- Internal Digitally Controlled Oscillator supports IEEE 1588 clock generation
- Jitter generation <0.65 ps RMS (10 k Hz to 20 MHz) meets jitter requirements of 1 Gb E PHYs and QSGMII
MAIN Features
- Digital PLL synchronizes with Ethernet connected synchronization sources
- DPLL bandwidth of 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 ppb and can be controlled by an external processor via I2C interface for IEEE 1588...
