SN75DP126DSRHUR

Specialized Overview

The SN75DP126DSRHUR is a DisplayPort 1:2 re-driver switch manufactured by Texas Instruments, housed in a WQFN-56 package. It operates at a supply voltage of 3.3 V with a typical operating current of 138 mA. The device supports DP v1.1a/v1.2 signaling up to HBR2 (5.4 Gbps) and HDMI 1.4b TMDS clock frequencies up to 340 MHz. It functions within an ambient temperature range of 0°C to +85°C. This component integrates a TMDS converter to switch a dual-mode DisplayPort input to either a DP++ output or a DVI/HDMI-compatible TMDS output.

Specialized Feature Summary
