• 16:1 Multiplexer Integrated with Clock

Multiplier and Laser Driver

• Monolithic Phase Locked Loop

• Laser Driver Provides up to 110 mA Current

• Differential 16-bit Parallel Data

• 100 pin 14x14 Plastic Quad Flat Package

• Jitter Generation Meets SONET OC-48 and

SDH STM-16 Requirements

plexer with Clock Recovery

• Supports Parity Checking at the 16-bit

Parallel Interface

General Description

The VSC8161 combines a Laser Driver and a clock multiplier with a 16:1 multiplexer to provide a single-

chip solution. The 16-bit data word is latched by an internal version of the reference clock, and is bit-multi-

plexed up to 2.488GHz. The on-chip PLL generates the internal 2.488GHz clock, which remains locked to the

155.52 MHz reference clock. The on-chip laser driver provides up to 60 mA modulation current and 50 mA bias

current.
