[1] ‘X’ signifies that PTN3700 handles this signal transparently, i.e., data is transmitted and received as-is.
[2] ‘R, G, B’ signifies that R, G, B video data have to be input according to the exact chosen pin configuration of
PTN3700, specifically:
a) Bit order reversal is not allowed, even if both the transmit data and receive data are reversed in bit order.
For example, the MSB of ‘R’ color from video source must be input as ‘R7’.
b) ‘R’ must be used for red color, ‘G’ for green color, and ‘B’ for blue color.
7.4.4.1 PSS mode
HS, VS and DE are treated by PTN3700 in the same way as RGB signals in PSS mode;
that is, HS, VS, and DE are serialized and transmitted transparently by the PTN3700
transmitter, and transparently received and deserialized by PTN3700 receiver. Data
Enable (DE) signal is typically used to signify the active display area from the non-active
display area.
In the case that advanced frame mixing is not used:
• DE signal can be tied HIGH or LOW, for displays not using DE signal.
• HS and VS can be active HIGH or active LOW.
7.4.4.2 FSS mode
In FSS mode, PTN3700 uses true source synchronous transmission with a serial
Double Data Rate (DDR) bit clock for the serial data.
FSS mode requires the following operating conditions:
• Active LOW HS
• Active LOW VS
• Active HIGH DE
In FSS mode, DE = 1 means active video, and PTN3700 generates embedded sync
words when DE = 0. DE, VS and HS must be actively driven according to the typical video
screen figure shown in Figure 18.
