3 Description
The LMH1219 is a low-power, dual-input and dual-
output, adaptive equalizer with integrated 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 is designed to equalize data
transmitted over 75 coaxial cable and operates
over a wide range of data rates from 125 Mbps to
11.88 Gbps. An adaptive board trace equalizer at IN1
is SFF-8431 compatible and supports both SMPTE
and 10 GbE data rates.
The integrated reclocker attenuates high frequency
jitter and provides the best signal integrity. High input
jitter tolerance of the reclocker improves timing
margin. The reclocker has a built-in loop filter, and
operates without the need of a precision input
reference clock. A non-disruptive eye monitor allows
real time measurement of the serial data to simplify
system debug and accelerate board bring-up.
The integrated 2:1 Mux and 1:2 Fanout provide
flexibility for multiple video signals. The output drivers
offer programmable de-emphasis to compensate
board trace losses at its outputs. The integrated
return loss network meets stringent SMPTE
specifications across all data rates. The typical power
consumption of LMH1219 is 250 mW. In the absence
of input signal, power is further reduced to 16 mW.
The LMH1219 is pin compatible to LMH1226 (12G
UHD reclocker) and LMH0324 (3G adaptive cable
equalizer).
