DescriptionThe STHDLS101T is a high-speed high-definition multimedia interface (HDMI) level shifter that converts low-swing AC coupled differential input to HDMI 1.3 compliant open-drain current steering RX-terminated differential output. Through the existing PCI-E pins in the graphics and memory controller hub (GMCH) of PCs or notebook motherboards, the pixel clock provides the required bandwidth (1.65Gbps, 2.25Gbps) for the video supporting 720p, 1080i, 1080p with a total of 36-bit resolution. The HDMI is multiplexed onto the PCIe pins in the motherboard where the AC coupled HDMI at 1.2V is output by GMCH. The AC coupled HDMI is then level shifter by this device to 3.3V DC coupled HDMI output. The STHDLS101T supports up to 2.7Gbps, which is enough for 12-bits of color depth per channel, as indicated in HDMI rev 1.3. The device operates from a single 3.3V supply and is available in a 48-pin QFN package.QFN-48(7x7mm)Table 1.Device summaryOrder codePackagePackagingSTHDLS101TQTRQFN-48Tap Features Converts low-swing alternating current (AC) coupled differential input to high-definition multimedia interface (HDMI) rev 1.3 compliant HDMI level shifting operation up to 2.7Gbps per lane Integrated 50- termination resistors for AC-coupled differential inputsInput/output transition minimized differential signaling (TMDS) enable/disableOutput slew rate control on TMDS outputs to minimize electromagnetic interference (EMI)Fail safe outputs for backdrive protectionNo re-timing or configuration requiredInter-pair output skew < 250 psIntra-pair output skew < 10psSingle power supply of 3.3VESD protection: 6KV HBM on all I/O pinsIntegrated display data channel (DDC) level shifters.
