描述

The 82V3203A is an integrated, single-chip solution for the Synchronous Equipment Timing Source (SETS) for Stratum 3, SMC, 4E and 4 clocks in SONET/SDH equipment, DWDM, and wireless base stations, such as GSM, 3G, DSL concentrator, router, and access network applications. The device supports three types of input clock sources: recovered clock from STM-N or OC-n, PDH network synchronization timing, and external synchronization reference timing. An input clock is automatically or manually selected for DPLL locking. The DPLL supports three primary operating modes: Free-Run, Locked, and Holdover. In Free-Run mode, the DPLL refers to the master clock. In Locked mode, the DPLL locks to the selected input clock. In Holdover mode, the DPLL resorts to the frequency data acquired in Locked mode. Whatever the operating mode is, the DPLL gives a stable performance without being affected by operating conditions or silicon process variations. If the DPLL outputs are processed by T0/T4 APLL, the outputs of the device will be in a better jitter/wander performance. The device provides programmable DPLL bandwidths, 0.1Hz to 560Hz in 11 steps, and damping factors, 1.2 to 20 in 5 steps. Different settings cover all SONET/SDH clock synchronization requirements. A highly stable input is required for the master clock in different applications. The master clock is used as a reference clock for all the internal circuits in the device. It can be calibrated within ± 741ppm. All the read/write registers are accessed only through an I2C programming interface.
