Gigabit Multimedia Serial Link with Spread
Spectrum and Full-Duplex Control Channel
MAX9259/MAX9260
______________________________________________________________________________________ 27
Parallel Inputs and Outputs
The parallel bus uses two selectable bus widths, 24
bits and 32 bits. BWS selects the bus width according
to Table 3. In 24-bit mode, DIN21–DIN28 are not used
and are internally pulled down. For both modes, SD,
SCK, and WS pins are dedicated for I2S audio data. The
assignments of the first 21 or 29 signals are interchange-
able and appear in the same order at both sides of the
serial link. In image-sensing applications, disabling the
I2S audio channel (through the MAX9259 and MAX9260
internal registers) allows the MAX9259 to serialize three
10-bit camera data streams through DIN[0:28] plus SD
inputs. The parallel bus accepts data clock rates from
8.33MHz to 104MHz for the 24-bit mode and 6.25MHz to
78MHz for the 32-bit mode.
Serial Link Signaling and Data Format
The MAX9259 high-speed data serial output uses
CML signaling with programmable preemphasis and
AC-coupling. The MAX9260 high-speed receiver uses
AC-coupling and programmable channel equalization.
Together, the GMSL operates at up to 3.125Gbps over
STP cable lengths up to 15m.
The MAX9259 serializer scrambles and encodes the
parallel input bits, and sends the 8B/10B coded sig-
nal through the serial link. The MAX9260 deserializer
recovers the embedded serial clock and then samples,
decodes, and descrambles the data onto the paral-
lel output bus. Figures 22 and 23 show the serial-data
packet format prior to scrambling and 8B/10B coding.
For the 24-bit or 32-bit mode, the first 21 or 29 serial
bits come from DIN[20:0] or DIN[28:0], respectively.
The audio channel bit (ACB) contains an encoded audio
signal derived from the three I2S inputs (SD, SCK, and
WS). The forward control channel (FCC) bit carries the
forward control data. The last bit (PCB) is the parity bit of
the previous 23 or 31 bits.
Reverse Control Channel
The MAX9259/MAX9260 use the reverse control channel
to send I2C/UART and interrupt signals in the opposite
direction of the video stream from the deserializer to
the serializer. The reverse control channel and forward
video data coexist on the same twisted pair forming a
bidirectional link. The reverse control channel operates
independently from the forward control channel. The
reverse control channel is available 500Fs after power-
up. The MAX9259 temporarily disables the reverse con-
trol channel for 350Fs after starting/stopping the forward
serial link.
