VSC8115 - STS-12/STS-3 Multi Rate Clock and Data Recovery Unit

Datasheet Summary

Description

The VSC8115 functions as a clock and data recovery (CDR) unit for SONET/SDH-based equipment to derive highspeed timing signals.

The VSC8115 recovers the clock from the scrambled non-return to zero (NRZ) data operating at 622.08 Mbps (STS-12/OC-12/STM-4) or 155.52 Mbps (STS-3/OC-3/STM-1).

Features

Performs clock and data recovery for 622.08 Mbps (STS-12/OC-12/STM-4) or 155.52 Mbps (STS-3/OC-3/STM-1) NRZ data.
19.44 MHz reference frequency LVTTL input.
Lock Detect output pin monitors data run length and frequency drift from reference clock.
Data is retimed at the output.
Active HIGH Signal Detect LVPECL input.
Low jitter, high-speed outputs support LVPECL and low-power LVDS.
Low power: 188 mW typical.
3.3 V power supply.
20-pin TSSOP package.
