The SN65LVCP1414RLJR is a 14.2-Gbps quad-channel, dual-mode linear equalizer (redriver) from Texas Instruments, packaged in a 38-pin WQFN (RLJ) 5 \u00d7 7 mm package. It is an asynchronous, protocol-agnostic, low-latency device optimized for compensating signal losses in backplane and active cable interconnects. The device supports both backplane and cable equalization modes with up to 17 dB of analog equalization at 7.1 GHz and is configurable via I2C or GPIO interface. Note: This part has been obsoleted; the substitute is SN65LVCP1414RLJT.<\/p>\n

It compensates for signal losses in backplane and active cable applications while preserving the transmitted signal waveform to ensure optimal decision feedback equalizer (DFE) performance. The device operates in dual mode \u2014 backplane or cable \u2014 with up to 17 dB of analog equalization at 7.1 GHz, adjustable in 1 dB steps. Configurable via I2C or GPIO, each channel can be independently controlled for equalization, path gain, and output dynamic range. The RLJR variant in 38-WQFN tape-and-reel packaging has been obsoleted; the substitute RLJT variant remains available.","working_principle":"The SN65LVCP1414 operates as a linear equalizer that amplifies and shapes incoming high-speed differential signals to compensate for frequency-dependent channel losses. The input stage accepts CML-level signals and applies programmable continuous-time linear equalization (CTLE) that selectively boosts high-frequency components attenuated by the PCB trace or cable. In backplane mode, the equalizer targets the loss profile typical of FR-4 traces; in cable mode, it addresses the different loss characteristic of copper cables. The equalized signal is then amplified through a programmable gain stage and delivered to the output driver with adjustable output dynamic range up to 1200 mV. The linear equalization approach preserves the signal waveform and noise profile, allowing downstream DFE circuits in the ASIC\/FPGA to perform optimal digital equalization. Configuration is managed through I2C registers (8-bit address map) or GPIO pins.","pin_description":"
