28-Bit GMSL Deserializer for Coax or STP Cable
24
Maxim Integrated
Serial Link Signaling and Data Format
The serializer uses differential CML signaling to drive
twisted-pair cable and single-ended CML to drive
coax cable with programmable pre/deemphasis and
AC-coupling. The deserializer uses AC-coupling and
programmable channel equalization.
Input data is scrambled and then 8b/10b coded. The
deserializer recovers the embedded serial clock, then
samples, decodes, and descrambles the data. In 24-bit
or 32-bit mode, 22 or 30 bits contain the video data
and/or error-correction bits, if used. The 23rd or 31st bit
carries the forward control-channel data. The last bit is
the parity bit of the previous 23 or 31 bits (Figure 15).
Reverse Control Channel
The serializer uses the reverse control channel to receive
I2C/UART and GPO signals from the deserializer in the
opposite direction of the video stream. The reverse
control channel and forward video data coexist on the
same serial cable, forming a bidirectional link. The
reverse control channel operates independently from the
forward control channel. The reverse control channel is
available 2ms after power-up. The serializer temporarily
disables the reverse control channel for 350Fs after start-
ing/stopping the forward serial link.
Data-Rate Selection
The serializer/deserializer use DRS, DBL, and BWS to set
the PCLKOUT frequency range (Table 3). Set DRS = 1
for a PCLKOUT frequency range of 6.25MHz to 12.5MHz
(32-bit, single-output mode) or 8.33MHz to 16.66MHz
(24-bit, single-output mode). Set DRS = 0 for normal
operation. It is not recommended to use double-output
mode when DRS = 1.
