SY89425 synthesizer equivalent, dual sonet oc-12 clock synthesizer.
s Two independently-powered 622.08MHz clock sources one chip s Differential PECL outputs s TTL/CMOS compatible inputs s SONET compliant jitter performance (≤0.01UI) s Cho.
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 ra.
