SY88343BL

3.3V, 3.2Gbps CML Limiting Post Amplifier

with High Gain TTL Loss-of-Signal

General Description

Features

The SY88343BL low-power limiting post amplifier is

designed for use in fiber-optic receivers. The device

connects to typical transimpedance amplifiers (TIAs)

that are AC-coupled. The linear signal output from TIAs

can contain significant amounts of noise and may vary

in amplitude over time. The SY88343BL quantizes these

signals and outputs CML-level waveforms.

• Single 3.3V power supply

• DC to 3.2Gbps operation

• Low-noise CML data outputs

• High gain LOS

• Chatter-free Open-Collector TTL Loss-of-Signal

(LOS) output with internal 4.75kΩ pull-up resistor

• TTL /EN input

• Programmable LOS level set (LOS_LVL

• Ideal for multi-rate applications

The SY88343BL 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 5mV_PPcan be

amplified to drive devices with CML inputs or AC-

coupled CML/PECL inputs.

• Available in a tiny 10-pin EPAD-MSOP and 16-pin

MLF^®package

The SY88343BL generates a high-gain loss-of-signal

(LOS) open-collector TTL output. The LOS function has

a high gain input stage for increased sensitivity. 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
