FEATURES
Description
The ZL30415 is an analog phase-locked loop (APLL) designed to provide jitter attenuation and rate conversion for SDH (Synchronous Digital Hierarchy) and SONET (Synchronous Optical Network) networking equipment. The ZL30415 generates low jitter output clocks that meet the jitter requirements of Telcordia GR-253-CORE OC-12, OC-3, OC-1 rates and ITU-T G.813 STM-4 and STM-1 rates.
Features
• Meets jitter requirements of Telcordia GR-253- CORE for OC-12, OC-3, and OC-1 rates
• Meets jitter requirements of ITU-T G.813 for STM- 4, and STM-1 rates
• Provides one differential LVPECL output clock selectable to 19.44 MHz, 38.88 MHz, 77.76 MHz, 155.52 MHz, or 622.08 MHz
• Provides a single-ended CMOS output clock at 19.44 MHz
• Accepts a single-ended CMOS reference at 19.44 MHz or a differential LVDS, LVPECL, or CML reference at 19.44 MHz or 77.76 MHz
• Provides a LOCK indication
• 3.3 V supply
Applications
• SONET/SDH line cards
