PIN FUNCTION DETAILS—DIGITAL INTERFACE
Digital Video Data Inputs
Rx0+
Digital Differential Input Channel 0 True
Rx0
Digital Differential Input Channel 0 Complement
Rx1+
Digital Differential Input Channel 1 True
Rx1
Digital Differential Input Channel 1 Complement
Rx2+
Digital Differential Input Channel 2 True
Rx2
Digital Differential Input Channel 2 Complement
These pins receive three pairs of differential, low
voltage, swing input pixel data from a digital
graphics transmitter.
Digital Video Clock Inputs
RxC+
Digital Differential Data Clock True
RxC
Digital Differential Data Clock Complement
These pins receive the differential, low voltage,
swing input pixel clock from a digital graphics
transmitter.
Termination Control
RTERM
Internal Termination Set Pin
This pin is used to set the termination resistance for
all digital interface high speed inputs. To set this pin,
place a resistor of 10 times the desired input termi-
nation resistance between this pin (Pin 53) and the
ground supply. Typically, the value of this resistor
should be 500 Ω.
Data Enable
DE
Data Enable
This pin outputs the state of data enable (DE). The
AD9887A decodes DE from the incoming stream of
data. The DE signal is high during active video and
low when there is no active video.
HDCP
DDCSCL HDCP Slave Serial Port Data Clock
For use in communicating with the HDCP-enabled
DVI transmitter.
DDCSDA HDCP Slave Serial Port Data I/O
For use in communicating with the HDCP-enabled
DVI transmitter.
MCL
HDCP Master Serial Port Data Clock
Connects the EEPROM for reading the encrypted
HDCP keys.
MDA
HDCP Master Serial Port Data I/O
Connects the EEPROM for reading the encrypted
HDCP keys.
CTL
Digital Control Outputs
These pins output the control signals for the red and
green channels. CTL0 and CTL1 correspond to the
red channel input, and CTL2 and CTL3 correspond
to the green channel input.
