Data Sheets:
The SY88053CL limiting post amplifier is designed for use in fiber-optic receivers for multi-rate applications from 1.0625Gbps to 12.5Gbps.
The SY88053CL contains a high-bandwidth, high-sensitivity input stage with user-programmable, wide-range SD assert/LOS de-assert threshold levels, which enables optimized system reach. Typically, 4dB of electrical hysteresis is provided to minimize LOS or SD chattering caused by noisy input signals. A logic level control pin is provided to enable user selection of an open-collector, TTL-compatible LOS or SD status indication signal with an external 5kΩ to 10kΩ pull-up resistor.
The SY88053CL provides fast SD assert and LOS de-assert times over the entire differential input voltage range of 5mVPP to 1800mVPP.
The SY88053CL input stage also provides a user-adjustable decision threshold circuit to optimize BER in noisy applications such as WDM, where EDFA and Raman amplifiers contribute uneven noise levels. By applying an external control voltage, the decision threshold can typically be adjusted from 30% to 70% from the nominal 50% threshold when the circuit is disabled.
The SY88053CL provides integrated 50Ω input and output impedances to optimize the high-speed signal paths and reduce component count. The post amplifier outputs have user-selectable polarity inversion control to simplify PCB layout. A TTL-compatible JAM input is provided to enable a SQUELCH function by feeding back the LOS or SD signal. The JAM input disables only the post amplifier output.
The SY88053CL operates from a single +3.3V power supply, over temperatures ranging from –40°C to +85°C.
