ZL30106 SONET/SDH/PDH Network Interface DPLL

The ZL30106 SONET/SDH/PDH network interface Digital Phase-Locked Loop (DPLL) provides timing and synchronization for SONET/SDH and PDH network interface cards. The ZL30106 generates SONET/SDH, PDH, ST-BUS and other TDM clock and framing signals that are phase locked to one of three network references. It helps ensure system reliability by monitoring its refe.

Features

• Synchronizes to clock-and-sync-pair to maintain minimal phase skew between inputs and outputs
• Supports output wander and jitter generation specifications for SONET/SDH and PDH interfaces
• Accepts three input references and synchronizes to any combination of 2 kHz, 8 kHz, 1.544 MHz, 2.048 MHz, 8.192 MHz, 16.384 MHz or 19.44 MHz inputs
• Provides a range of clock outputs: - 2.048 MHz (E1), 16.384 MHz and either 4.096 MHz and 8.192 MHz or 32.768 MHz and 65.536 MHz - 19.44 MHz (SONET/SDH) - 1.544 MHz (DS1) and 3.088 MHz - a choice of 6.312 MHz (DS2), 8.448 MHz (E2), 44.736 MHz (DS3) or 34.368.
