AD8098 Product Details

The AD8098 provides a 155.52 MHz ECL/PECL output clock from either a 19.44 MHz or a 9.72 MHz TTL/CMOS/ECL/PECL reference frequency. The AD8098 functionality supports a distributed timing architecture, allowing a backplane or PCB 19.44 MHz or 9.72 MHz timing reference signal to be distributed to multiple 155.52 Mbps ports. The AD8098 can be applied to create the transmit bit clock for one or more ports.

An input signal multiplexer supports loop-timed applications where a 155.52 MHz transmit bit clock is recovered from the 155.52 Mbps received data.

The low jitter VCO, low power and wide operating temperature range make the device suitable for generating a 155.52 MHz bit clock for SONET/SDH/Fiber in the Loop systems.

The device has a low cost, on-chip VCO that locks to either 8x or 16x the frequency at the 19.44 MHz or 9.72 MHz input. No external components are needed for frequency synthesis; however, the user can adjust loop dynamics through selection of a damping factor capacitor whose value determines loop damping.

The AD8098 design guarantees that the clock output frequency will drift low (by roughly 20%) in the absence of a signal at the input.

The AD8098 consumes 90 mW and operates from a single power supply at either +5 V or -5.2 V.
