Note: The connector pin-out depends on which end of the cable it is connected. (See

Table 1-1 and Table 1-2 for the transmit and receive pinouts.)

Signal Descriptions

The DVP interface features differential, 5-volt positive-ECL (5V-PECL) signalling. This

document uses the UNIX

syntactic convention of “curly braces” to show alternatives for

the signal polarity. This convention allows a single name to refer to both of the signals in

the differential pair, yet makes it obvious that there are two signals. (In actual schematics,

each differential pair signal has its own name with the polarity speciﬁed and the curly

braces omitted. For example, this document might describe a differential pair as

FOO_{H,L}, whereas actual schematics would show the pair of signals as FOO_H and

FOO_L.)

Video Data

There are 72 video data signals, which comprise 36 differential signal pairs. These are

split into three color components of 12 bits each: (RED_OUT_{H,L}[11:0],

GREEN_OUT_{H,L}[11:0], BLUE_OUT_{H,L}[11:0]). The InﬁniteReality DVP interface

does not include the Alpha channel.

This document uses the following video data signal naming convention:

ColorComponentName_OUT_SignalPolarity[SigniﬁcantBit]. The last digit of the signal

name indicates the binary signiﬁcance of the digital color component. For example, the

most signiﬁcant bit of the positive-logic version green component is

GREEN_OUT_H[11].
