The LMH1226 is a low-power, dual-output 12G UHD 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 adaptive board trace equalizer at IN1 is SFF-8431 compatible and supports both SMPTE and 10 GbE data rates.
The reclocker attenuates high frequency jitter and provides the best signal integrity. High input jitter tolerance of the reclocker improves timing margin. The reclocker has built-in loop filter and operates without the need of a precision input reference clock. A non-disruptive eye monitor allows for real time measurement of the serial data to simplify system debug and accelerate board bring-up.
The integrated 1:2 fanout provides flexibility for multiple video signals. The output drivers offer programmable de-emphasis to compensate board trace losses at its outputs. The typical power consumption of LMH1226 is 214 mW. In the absence of input signal, power is further reduced to 16 mW.
The LMH1226 is pin compatible with the LMH1219 (12G-UHD cable equalizer with integrated reclocker).
