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, or 77.76MHz. When using both PLLs, it is not necessary that .
