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 (LOSLVL  
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 –40oC to +85oC.  
Signals with data rates from 155Mbps up to 3.2Gbps,  
and as small as10mVpp, 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 (LOSLVL) sets the sensitivity of the input  
amplitude detection. LOS asserts high if the input  
amplitude falls below the threshold sets 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, 3.3dB LOS hysteresis is provided to  
prevent chattering.
