www.DataSheet4U.com STHDLS101 AC coupled HDMI level shifter 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 2.7 Gbps per lane Integrated 50 Ω termination resistors for AC-coupled differential inputs Input/output transition minimized differential signaling (TMDS) enable/disable Output slew rate control on TMDS outputs to minimize electromagnetic interference (EMI) Fail-safe outputs for backdrive protection No re-timing or configuration required Inter-pair output skew < 250 ps Intra-pair output skew < 10 ps Single power supply of 3.3 V ESD protection: ±6 KV HBM on all I/O pins Integrated display data channel (DDC) level shifters. Pass-gate voltage limiters allow 3.3 V termination on graphics and memory controller hub (GMCH) pins and 5 V DDC termination on HDMI connector pins Hot-plug detect (HPD) signal level shifter from HDMI/DVI connector Integrated pull-down resistor on HPD_SINK and OE_N inputs QFN-48 (7 x 7 mm) ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Description The STHDLS101 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 (1.65 Gbps,...
