SY88289AL

3.3V, 3.2Gbps CML Low-Power Limiting

Post Amplifier with TTL Loss-of-Signal

General Description

Features

The SY88289AL low-power limiting post amplifier is

designed for use in fiber-optic receivers. The device

connects to typical transimpedance amplifiers (TIAs).

The linear signal output from TIAs can contain

significant amounts of noise and may vary in amplitude

over time. The SY88289AL quantizes these signals and

outputs CML-level waveforms.

• Single 3.3V power supply

• 125Mbps to 3.2Gbps operation

• Low-noise CML data outputs

• Chatter-free open-collector TTL Loss-of-signal (LOS)

output with internal 4.75kΩ pull-up resistor

• TTL /EN input

• Internal 50Ω input termination

• Programmable LOS level set (LOS_LVL

• Ideal for multi-rate applications

• Available in a tiny 3mmx3mm 16-pin QFN package

The SY88289AL operates from a single +3.3V power

supply, over temperatures ranging from –40^oC to +85^oC.

With its wide bandwidth and high gain, signals with data

rates up to 3.2Gbps, and as small as 10mV_P-P, can be

amplified to drive devices with CML inputs or AC-

coupled CML/PECL inputs.

Applications

The SY88289AL generates a loss-of-signal (LOS) open-

collector TTL output. A programmable loss-of-signal

level-set pin (LOS_LVL) sets the sensitivity of the input

amplitude detection. LOS asserts high if the input

amplitude falls below the threshold set by LOS_LVLand

de-asserts low otherwise. The enable bar input (/EN)

de-asserts the true output signal without removing the

input signal. The LOS output can be fed back to the /EN

input to maintain output stability under a loss-of-signal

condition. Typically, 3.5dB LOS hysteresis is provided to

prevent chattering.
