TMDS250

SLLS866 – AUGUST 2007

The TMDS250 provides two levels of receiver input equalization for different ranges of cable lengths. Each

TMDS receiver owns frequency responsive equalization circuits. When EQ sets low, the receiver supports the

input connection in short range HDMI cables. When EQ sets high, the receiver supports the input connection in

long range HDMI cables. The TMDS250 supports power saving operation. When a system is under standby

mode and there is no digital audio/visual content from a connected source, the 3.3-V supply voltage, VCC, can be

powered off to minimize power consumption from the TMDS inputs, outputs, and internal switching circuits. The

HPD, DDC, and source selection circuits are powered up by the 5-V supply voltage, VDD, to maintain the system

hot plug detect response, the DDC link from the selected source to the sink under system standby operation. The

device is characterized for operation from 0

°C to 70°C.
