STHDLS101
Overview
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, 2.25 Gbps) for the video supporting 720p, 1080i, 1080p with a total of 36-bit resolution.
- 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
