SY88345BL  
3.3V, 3.2Gbps CML Low-Power Limiting Post  
Amplifier w/ High-Gain TTL Signal Detect  
Features  
General Description  
Single 3.3V power supply  
155Mbps to 3.2Gbps operation  
Low-noise CML data outputs  
Chatter-free Open-Collector TTL signal detect (SD)  
output with internal 4.75kpull-up resistor  
The SY88345BL high-sensitivity limiting post amplifier is  
designed for use in fiber-optic receivers. 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 SY88345BL quantizes these signals and  
outputs CML-level waveforms.  
TTL EN input  
Internal 50input termination  
Programmable SD level set (SDLVL  
Ideal for multi-rate applications  
The SY88345BL operates from a single +3.3V +10%  
power supply, over temperatures ranging from –40oC to  
+85oC. With its wide bandwidth and high gain, signals  
with data rates up to 3.2Gbps and as small as 5mVPP  
can be amplified to drive devices with CML inputs or AC-  
coupled CML/PECL inputs.  
)
Available in a tiny 10-pin EPAD MSOP and 16-pin  
MLF® package  
The SY88345BL generates a signal-detect (SD) open-  
collector TTL output. A programmable signal-detect  
level-set pin (SDLVL) sets the sensitivity of the input  
amplitude detection. SD asserts high if the input  
amplitude rises above the threshold sets by SDLVL and  
de-asserts low otherwise. The enable input (EN) de-  
asserts the true output signal without removing the input  
signal. The SD output can be fed back to the EN input to  
maintain output stability under loss-of-signal condition.  
Typically, 3.5dB SD hysteresis is provided to prevent  
chattering.  
Applications  
APON/BPON, EPON, GPON and GEPON  
Gigabit Ethernet  
1X and 2X Fibre Channel  
SONET/SDH: OC-3/12/24/48–STMD/4/8/16  
High-gain line driver and line receiver  
Markets  
FTTP/FTTH
