SY88083LMG-TR Product Details

The SY88083LMG-TR limiting post amplifier is designed for use in fiber-optic receivers for continuous mode, multi-rate applications from 1Gbps to 12.5Gbps.

The SY88083LMG-TR 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 SY88083LMG-TR provides faster SD assert and LOS de-assert times than typical continuous mode devices over the entire differential input voltage range of 10mVPP to 1800mVPP.

The SY88083LMG-TR input stage also provides a user-selectable digital offset correction (DOC) function to automatically compensate for internal device offsets in the high-speed data path.

The SY88083LMG-TR provides integrated 50Ω input and output impedances to optimize the high-speed signal paths and reduce component count. 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 SY88083LMG-TR operates from a single +3.3V power supply, over temperatures ranging from –40°C to +85°C.
