SY88903AL  
3.3V, Burst Mode 1.25Gbps PECL High-  
Sensitivity Limiting Post Amplifier with TTL  
Loss-of-Signal  
General Description  
Features  
The SY88903AL, burst mode, high-sensitivity limiting  
post amplifier is designed for use in fiber-optic receivers,  
specially optimized for passive optical networks (PONs).  
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 SY88903AL quantizes these  
signals and outputs PECL level waveforms.  
Single 3.3V power supply  
Fast LOS release/assert (<500ns) time for PON  
applications  
622Mbps to 1.25Gbps operation  
Low-noise PECL data outputs  
High gain LOS  
Chatter-free Open-Collector TTL signal detect (LOS)  
output with internal 4.75kpull-up resistor  
The SY88903AL operates from a single +3.3V power  
supply, over temperatures ranging from –40oC to +85oC.  
Signals with data rates from 622Mbps up to 1.25Gbps,  
and as small as 5mVpp, can be amplified to drive  
devices with PECL inputs.  
TTL /EN input  
Programmable LOS level set (LOSLVL  
Available in a tiny 10-pin MSOP package  
)
The SY88903AL generates a Loss-of-Signal (LOS)  
open-collector TTL output. A programmable Loss-of-  
Signal level set pin (LOSLVL) sets the sensitivity of the  
input amplitude detection. LOS asserts high if the input  
amplitude falls below the threshold set by LOSLVL and  
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, 3.4dB LOS hysteresis is provided to  
prevent chattering.  
Applications  
GPON/GEPON/EPON  
Gigabit Ethernet, 1062Mbps Fibre Channel  
OC-12/24 SONET/SDH  
Low-gain TIA interface  
High-gain line driver and line receiver  
Markets
