Texas Instruments LMH1239EVM Reclocker Evaluation Module (EVM)

Texas Instruments LMH1239EVM Reclocker Evaluation Module (EVM) is designed for high-speed performance and functional evaluation of the Texas Instruments LMH1239 12G UHD long-reach cable equalizer with integrated reclocker and input mux. This kit lets users quickly evaluate the cable reach and output signal integrity supported by the LMH1239. High-performance edge mount BNC connectors are used at the 75Ω port for the SDI_IN and SDI_OUT signals, while 100Ω differential output ports are routed to edge mount SMA connectors. These connectors facilitate connection to lab equipment or user systems for performance evaluation. An onboard MSP430 MCU is included to support an optional SMBus or SPI serial control interface when configuring the LMH1239 operating modes.
