The SN65LVCP1412 is an asynchronous, protocol-agnostic, low latency, two-channel linear equalizer optimized for use up to 14.2Gbps and compensates for losses in backplane or active cable applications. The architecture of SN65LVCP1412 is designed to work with an ASIC or a FPGA with digital equalization employing Decision Feedback Equalizers (DFE). SN65LVCP1412 linear equalizer preserves the shape of the transmitted signal ensuring optimum DFE performance. SN65LVCP1412 provides a low power solution while at the same time extending the effectiveness of DFE.

SN65LVCP1412 is configurable via I2C or GPIO interface. Using the I2C interface of the SN65LVCP1412 enables the user to control independently the Equalization, Path Gain, and Output Dynamic Range for each individual channel. In GPIO mode, Equalization, Path Gain, and Output Dynamic Range can be set for all channels using the GPIO Input pins.

SN65LVCP1412 outputs can be disabled independently via I2C.

The SN65LVCP1412 operates from a single 2.5V or 3.3V power supply.

The package for the SN65LVCP1412 is a 24 pin 4mm x 5mm x 0.75mm QFN (Quad Flatpack, No-lead) lead-free package with 0.5mm pitch, and characterized for operation from –40°C to 85°C.
