Description

OUT_D2+

TMDS Differential output

HDMI 1.3 compliant TMDS output. OUT_D2+ makes

a differential output signal with OUT_D2–.

OUT_D2–

TMDS Differential output

HDMI 1.3 compliant TMDS output. OUT_D2– makes

a differential output signal with OUT_D2+.

OUT_D1+

TMDS Differential output

HDMI 1.3 compliant TMDS output. OUT_D1+ makes

a differential output signal with OUT_D1–.

OUT_D1–

TMDS Differential output

HDMI 1.3 compliant TMDS output. OUT_D1– makes

a differential output signal with OUT_D1+.

HPD_SINK

5V tolerance single-ended input Low Frequency, 0V to 5V (nominal) input signal. This

signal comes from the HDMI connector. Voltage High

indicates "plugged" state; voltage low indicated

"unplugged". HPD_SINK is pulled down by an

integrated 100K ohm pulldown resistor.

HPD_SOURCE

3.3V single-ended output

HPD_SOURCE: 0V to 3.3V (nominal) output signal.

This is level-shiftedversion of the HPD_SINK signal.

SCL_SOURCE

Single-ended 3.3V open-drain

DDC I/O

3.3V DDC Data I/O. Pulled up by external termina-

tion to 3.3V. Connected to SCL_SINK through volt-

age-limiting intergrated NMOS passgate.

SDA_SOURCE

Single-ended 3.3V open-drain

DDC I/O

3.3V DDC Data I/O. Pulled up by external termination

to 3.3V. Connected to SDA_SINK through voltage-

limiting intergrated NMOS passgate.

SCL_SINK

Single-ended 5V open-drain

DDC I/O

5V DDC Clock I/O. Pulled up by external termination

to 5V. Connected to SCL_SOURCE through voltage-

limiting integrated NMOS passgate.

SDA_SINK

Single-ended 5V open-drain

DDC I/O

5V DDC Data I/O. Pulled up by external termination

to 5V. Connected to SDA_SOURCE through voltage-

limiting integrated NMOS passgate.

DDC_EN

5.0V tolerant Single-ended input Enables bias voltage to the DDC passgate level shifter

gates. (May be implemented as a bias voltage connec-

tion to the DDC pass gates themselves.)

(REXT)

3.3V single-ended control input

Acceptable connections to OC_1 (REXT) pin are: Re-

sistor to GND; Resistor to 3.3V; NC. (Resistor should

be 0-ohm).

Note:

1) internal 100Kohm pull-up
