SY88353BL

3.3V, 3.2 Gbps Limiting Post Amplifier with

Programmable Decision Threshold

General Description

Features

The SY88353BL limiting post amplifier is designed for

use in fiber-optic receivers, and is specially optimized for

WDM applications where optical amplifiers such as

EDFAs and Raman amplifier are used. The device

connects to typical transimpedance amplifiers (TIAs).

The linear signal from TIAs can contain significant

amounts of noise that is unevenly distributed between

top and bottom rails due to the ASE noise generated by

the optical amplifiers, crosstalk, or non-linear effect in

the fiber. In order to optimize the BER in such noisy

conditions, the decision threshold between bit 1 and bit

0, needs to be moved to the rail that contains less noise.

The SY88353BL features a pin at which an external

voltage can be applied to move the crossing point up

and down, from 20% to 80%, for BER optimization

purposes.

• Single 3.3V power supply

• Fast LOS release/assert

• 155Mbps to 3.2Gbps operation

• Low-noise CML data outputs

• Chatter-free Open-Collector TTL loss-of-signal (LOS)

output.

• TTL /EN input

• Programmable LOS level set (LOS_LVL

• Programmable Decision Threshold

)

• Available in a tiny 3mm x 3mm MLF™ package

Applications

• WDM Systems

• Gigabit Ethernet, 1X and 2X Fibre Channel

• SONET/SDH: OC-3/12/24/48 – STM1/4/8/16

• Low-gain TIA interface

The SY88353BL operates from a single +3.3V power

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

Signals with data rates from 155Mbps up to 3.2Gbps,

and as small as10mV_pp, can be amplified to drive

devices with CML or PECL inputs.

Markets

The SY88353L features 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 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 output stability under a loss-of-signal

condition. Typically, 3.3dB LOS hysteresis is provided to

prevent chattering.
