across the REXT. The differential output driver provides a typical 10 mA current sink
capability, which provides a typical 500 mV voltage drop across a 50
TMDS voltage levels
The TMDS interface standard is a signaling method intended for point-to-point
communication over a tightly controlled impedance medium. The TMDS standard uses a
lower voltage swing than other common communication standards, achieving higher data
rates with reduced power consumption while reducing EMI emissions and system
susceptibility to noise. The device is capable of detecting differential signals as low as
100 mV within the entire common mode voltage range.
Operating modes
Table 4.
The OE_N input activates a hardware power down mode. When the power down mode is
active (OE_N = H), all input and output buffers and internal bias circuitry are powered-off
and disabled.
Outputs are tri-stated in power-down mode. When exiting power-down mode, there is a
delay associated with turning on band-references and input/output buffer circuits.
