General 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).

After the clock is recovered, the data is retimed using an output flip-flop.

Overview

VSC8115 Datasheet STS-12/STS-3 Multirate Clock and Data Recovery.

Key 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.
