SY88307BL

3.3V, 3.2Gbps PECL Limiting Post Amplifier

with Wide Loss-of-Signal Detection Range

General Description

Features

The SY88307BL low-power limiting post amplifiers are

designed for use in fiber-optic receivers. These devices

connect 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 SY88307BL quantizes these signals and output

PECL-level waveforms.

• Loss-of-signal detection circuit optimized to detect a

wide input range (20mV_PP-140mV_PP)

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

(LOS) output

• Single 3.3V power supply

• 155Mbps to 3.2Gbps operation

• Low-noise PECL data outputs

The SY88307BL operates from a single +3.3V power

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

With their wide bandwidth and high gain, signals with

data rates up to 3.2Gbps, and as small as 10mV_PP, can

be amplified to drive devices with PECL/CML inputs.

• Programmable LOS level set (LOS_LVL

)

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

QFN package

Applications

The SY88307BL generates a loss-of-signal (LOS) open-

collector TTL output. The LOS function is optimized to

detect a wide input range, as shown in the typical

• SONET/SDH:OC 3/12/24/48 – STM 1/4/8/16

• High-gain line driver and line receiver

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 sets 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
