SY89425, DUAL SONET OC-12 CLOCK SYNTHESIZER
Micrel-Synergy's SY89425 Dual Phase Locked Loop (PLL) consists of two totally separate, SONET compliant 622.08MHz clock generators on one chip.
The user may select to power both PLLs or PLL A only.
Each PLL produces a low-jitter OC-12/STS-12 clock rate from an input reference clock of 38.88, 51.84,
