User Guide:
The SY88083L limiting post amplifier is designed for use in fiber-optic receivers for continuous mode, multi-rate applications from 1Gbps to 12.5Gbps.
The SY88083L 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 SY88083L 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 SY88083L 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 SY88083L 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 SY88083L operates from a single +3.3V power supply, over temperatures ranging from –40°C to +85°C.
- Multi-rate operation from 1.0625Gbps to 12.5Gbps
- Selectable digital offset correction for internal offset compensation in the high-speed data path
- Wide differential input range (10mVPP to 1800mVPP)
- Wide SD de-assert or LOS assert threshold range
- 4.5mVPP to 30mVPP
- 4dB typical electrical hysteresis
- Fast SD assert and LOS de-assert times
- 1µs typical; 2µs maximum
- Selectable LOS or SD status signal indicator
- TTL-compatible JAM input with internal pull-up
- Low-noise CML data inputs with integrated 50Ω termination impedance to internal reference VREF
- Low-noise CML data outputs with integrated 50Ω termination impedance
- 30ps typical rise/fall times
- Wide range power supply: 3.3V ±10%
- Industrial temperature range: -40°C to +85°C
- Available in a tiny 3mm x 3mm QFN package
