SY88349NDL  
2.5Gbps Burst-Mode Limiting Amplifier  
with Ultra-Fast Signal Assert Timing  
General Description  
Features  
The SY88349NDL is  
a
high-sensitivity, burst-mode  
<5ns SD assert (LOS deassert) time  
Proprietary noise discriminator feature  
capable limiting post amplifier designed for optical line  
terminal (OLT) receiver applications. The SY88349NDL  
satisfies the strict timing restrictions of the GPON  
standards by providing ultra-fast loss-of-signal (LOS) or  
Signal-Detect (SD) output. Auto reset and manual reset  
options are provided to control LOS/SD output timing. For  
increased flexibility, this device also includes an option to  
select between LOS or SD output. The device can be  
connected to burst-mode capable transimpedance  
amplifiers (TIAs) using AC or DC coupling.  
Option to AUTO RESET or manual RESET LOS/SD  
output  
Selectable LOS/SD option  
Up to 2.5Gbps operation  
Low-noise CML data outputs  
5mVpp input sensitivity  
High-sensitivity LOS/SD detect  
LVTTL LOS/SD output with an external pull-up resistor  
Squelching function to disable output  
Programmable LOS/SD level set (LOS/SDLVL  
Single 3.3V power supply  
The SY88349NDL generates a high-gain LOS or SD  
LVTTL output. A programmable LOS/SD level set pin  
(LOS/SDLVL) sets the sensitivity of the input amplitude  
detection. When LOS/SD SEL pin is left open or tied to  
VCC, JAM is active high, SD is selected and asserts high if  
the input amplitude rises above the threshold sets by  
LOS/SDLVL and de-asserts low otherwise. When LOS/SD  
SEL pin is set low or tied to GND, JAM is active low, LOS  
is selected and asserts low if the input amplitude rises  
above the threshold sets by LOS/SDLVL and de-asserts  
high otherwise. The LOS/SD output can be fed back to the  
JAM input to maintain output stability under an invalid  
signal conditions. Typically, 4dB 5dB SD hysteresis is  
provided to prevent chattering.  
)
Available in a 16-pin (3mm 3mm) QFN package  
Applications  
XGPON.1/GEPON/GPON  
Gigabit Ethernet  
Fibre Channel  
OC-3/12/24/48 SONET/SDH  
High-gain line driver and line receiver  
Low-gain TIA interface  
The SY88349NDL also features a selectable proprietary  
noise discriminator that aids by filtering out input signals  
that do not qualify as a 2.5Gbps GPON preamble signal in  
the initial startup phase. This feature minimizes false SD  
asserts that can be triggered by random noise.  
Markets  
FTTH  
Datacom/Telecom  
Optical transceiver  
The SY88349NDL operates from a single +3.3V power  
supply, over temperatures ranging from –40C to +85C.  
With its wide bandwidth and high gain, signals up to  
2.5Gbps and as small as 5mVpp can be amplified to drive  
devices with CML inputs.
