The LMH0324 is a low-power, dual-output, extended reach adaptive cable equalizer. It is designed to equalize SDI data transmitted over 75-Ω coax cable. The equalizer operates over a wide range of data rates from 125 Mbps to 2.97 Gbps. The equalizer includes an active sensing circuitry that ensures robust performance and enhanced immunity to variations in the input signal launch amplitude.

The LMH0324 provides extended cable reach with low power consumption. It offers power management to reduce power consumption further when no input signal is present.

The LMH0324 has two differential serial data outputs, which provide flexibility for fan-out buffering. The output drivers offer programmable de-emphasis to compensate for board trace losses at the LMH0324 outputs. The operating state of the LMH0324 can be set via pin control. Additional settings of the device can be programmed via SPI or SMBus interface.

The LMH0324 is pin-compatible to the LMH1219 (12-Gbps adaptive cable equalizer with integrated reclocker). The pin compatibility allows ease of upgrade from a 3-Gbps equalizer to a 12-Gbps equalizer with integrated reclocker.
