SN65LVCP1414RLJT General Description

The SN65LVCP1414 is an asynchronous, protocol-agnostic, low latency, four-channel linear equalizer optimized for use up to 14.2Gbps and compensates for losses in backplane or active cable applications. The architecture of the SN65LVCP1414 is designed to work with an ASIC or FPGA with digital equalization employing Decision Feedback Equalizers (DFE). The SN65LVCP1414 linear equalizer preserves the shape of the transmitted signal ensuring optimum DFE performance. The SN65LVCP1414 provides a low power solution while at the same time extending the effectiveness of DFE.

The SN65LVCP1414 is configurable via I2C or GPIO interface. Using the I2C interface of the SN65LVCP1414 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.

The SN65LVCP1414 outputs can be disabled independently via I2C.

The SN65LVCP1414 operates from a single 2.5V or 3.3V power supply.

The package for the SN65LVCP1414 is a 38 pin 5-mm × 7-mm × 0.75-mm QFN (Quad Flat-pack No-lead) lead-free package with 0.5mm pitch and is characterized for operation from –40°C to 85°C.
