Limiting post amplifiers operational at 12.5Gbps
14.00
They could also find use in continuous mode fibre optic or copper cable SFP+ transceiver modules for multi-rate applications from 1G to 12.5Gbps.
Both devices offer user selectable LOS or SD status signals and a wide differential input voltage range of 10mVPP to 1800mVPP for extended link distance operation. Electrical hysteresis of 4dB is provided across a wide LOS/SD threshold range of 4.5mVPP to 30mVPP. Integrated 50 Ohm input and output impedances with CML output, with 30ps typical rise/fall times, optimize high speed signal integrity while reducing external component counts and BOM cost.
The TTL compatible JAM input enables a SQUELCH function by routing back the LOS or SD signal. Other features include selectable RXOUT+ / RXOUT- signal polarity (SY88073L).
The SY88073L enables user adjustable decision threshold adjustment for optimized Bit Error Rate operation in noisy applications with asymmetrical noise distribution while the SY88083L provides a user selectable Digital Offset Correction function that automatically compensates for internal device offsets in the high speed data path.
Both devices offer a wide power supply range of 3.3V +/-10 percent and come in an industrial temperature range of 40-degC to +85-degC and a tiny 3mm x 3mm, 16 lead QFN package.
