LMH1219RTWT Product Details

The LMH1219RTWT is a low-power, dual-input and dual-output, adaptive equalizer withintegrated reclocker. It supports SMPTE video rates up to 11.88 Gbps and 10 GbE video over IP,enabling UHD video for 4K/8K applications. An extended reach adaptive cable equalizer at IN0 isdesigned to equalize data transmitted over 75 ? coaxial cable and operates over a wide range ofdata rates from 125 Mbps to 11.88 Gbps. An adaptive board trace equalizer at IN1 is SFF-8431compatible and supports both SMPTE and 10 GbE data rates.

The integrated reclocker attenuates high frequency jitter and provides the best signalintegrity. High input jitter tolerance of the reclocker improves timing margin. The reclocker has abuilt-in loop filter, and operates without the need of a precision input reference clock. Anon-disruptive eye monitor allows real time measurement of the serial data to simplify system debugand accelerate board bring-up.

The integrated 2:1 Mux and 1:2 Fanout provide flexibility for multiple video signals. Theoutput drivers offer programmable de-emphasis to compensate board trace losses at its outputs. Theintegrated return loss network meets stringent SMPTE specifications across all data rates. Thetypical power consumption of LMH1219RTWT is 250 mW. In the absence of input signal, power is furtherreduced to 16 mW.

The LMH1219RTWT is pin compatible to LMH1226 (12G UHD reclocker) and LMH0324 (3G adaptivecable equalizer).
