General Description

The SY84113BU low power limiting post amplifier is

designed for use in fiber-optic optical modules for

multirate applications up to 1.25Gbps. The device

connects to a typical transimpedance amplifier (TIA) and

can produce output signals to CML-level waveforms.

Intended for the GbE and Fibre Channel applications,

the SY84113BU offers a wide LOS range. It is able to

detect input signals for as low as 5mVpp and as high as

100mVpp. The SY84113BU is intended to be used in

AC-coupled input applications.

The SY84113BU generates a Loss-of-Signal (LOS)

open-collector TTL output. A programmable Loss-of-

Signal level set pin (LOS

input amplitude detection. LOS asserts high if the input

amplitude falls below the threshold set by LOS

de-asserts low otherwise. The enable 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 implement the squelch function that maintains output

stability under a loss-of-signal condition.

The SY84113BU operates on a single 2.5V power

supply and offers ultra low power consumption. This

device is perfectly suited to meet the stringent power

requirements of the CSFP/SFP/SFF optical modules.
