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

QFN-48

signaling (TMDS) enable/disable

(7 x 7 mm)

■ 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

Description

■ Intra-pair output skew < 10 ps

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.±5 Gbps, 2.25 Gbps)

for the video supporting 720p, 1080i, 1080p with a

total of 3±-bit resolution. The HDMI is multiplexed

onto the PCIe pins in the motherboard where the

AC coupled HDMI at 1.2 V is output by GMCH.

The AC coupled HDMI is then level shifter by this

device to 3.3 V DC coupled HDMI output. The

STHDLS101 supports up to 2.7 Gbps, which is

enough for 12 bits of color depth per channel, as

indicated in HDMI rev 1.3. The device operates

from a single 3.3 V supply and is available in a

48-pin QFN package.

■ Single power supply of 3.3 V

■ ESD protection: ±± 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

Applications

■ Notebooks

■ PC motherboards and graphic cards

■ Dongles/cable adapters
