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).
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.
