It supports both DVB-ASI and SMPTE standards, meaning it handles the two dominant serial protocols in broadcast and professional video infrastructure. This part lives in the receive path of a video distribution amplifier, a production switcher, or a fiber-optic transport link. ## Package and board-fit details Packaged in a 20-lead PowerTSSOP with an exposed pad (20-HTSSOP). The control interface is serial, so the configuration registers are programmed over a two-wire bus rather than parallel pins. This keeps the pin count low for the 20-lead package but means the downstream FPGA or microcontroller must have a serial port available at power-up.","metaTitle":"Texas Instruments LMH0346MH/NOPB Reclocker, DVB-ASI/SMPTE","metaDescription":"Texas Instruments LMH0346MH/NOPB video reclocker for professional video.
