SD SDI reclocker for broadcast video chains
The Texas Instruments LMH0026MH/NOPB is a standard-definition SDI reclocker designed to clean up serial digital video signals in professional video infrastructure. The part operates from a 3.135V to 3.465V supply and is configured through a serial control interface, which keeps the BOM simple—no external PLL loop filter components needed for the basic reclocker function.
3.3V supply and signal compatibility
The supply range covers 3.3V nominal with 5% tolerance, so the LMH0026MH/NOPB runs cleanly off a standard 3.3V rail without an extra regulator. The serial control interface is 3.3V-logic compatible, which simplifies connection to a host MCU or FPGA—no level shifting for the configuration lines. The reclocker's input and output are AC-coupled, per SDI practice, and the 20-HTSSOP package keeps the thermal path short for the modest dissipation typical of an SDI reclocker.
