Gigabit Multimedia Serial Link with Spread
Spectrum and Full-Duplex Control Channel
General Description
The MAX9259/MAX9260 chipset presents Maxim’s
gigabit multimedia serial link (GMSL) technology. The
MAX9259 serializer pairs with the MAX9260 deserializer
to form a complete digital serial link for joint transmission
of high-speed video, audio, and control data.
The MAX9259/MAX9260 allow a maximum serial payload
data rate of 2.5Gbps for a 15m shielded twisted-pair
(STP) cable. The 24-bit or 32-bit width parallel interface
operates up to a maximum bus clock of 104MHz or
78MHz, respectively. This serial link supports display
panels from QVGA (320 x 240) up to XGA (1280 x 768),
or dual-view WVGA (2 x 854 x 480).
The 24-bit or 32-bit mode handles 21 or 29 bits of data,
along with an I²S input, supporting 4- to 32-bit audio
word lengths and an 8kHz to 192kHz sample rate. The
embedded control channel forms a full-duplex, differen-
tial 100kbps to 1Mbps UART link between the serializer
and deserializer. The host electronic control unit (ECU)
or microcontroller (FC) resides either on the MAX9259
(for video display) or on the MAX9260 (for image sens-
ing). In addition, the control channel enables ECU/FC
control of peripherals in the remote side of the serial link
through I²C (base mode) or a user-defined full-duplex
UART format (bypass mode).
The MAX9259 serializer driver preemphasis and chan-
nel equalizer on the MAX9260 extend the link length and
enhance the link reliability. Spread spectrum is available
on the MAX9259/MAX9260 to reduce EMI on the serial
and parallel output data signals. The differential link
complies with the ISO 10605 and IEC 61000-4-2 ESD-
protection standards.
The core supplies for the MAX9259/MAX9260 are 1.8V
and 3.3V, respectively. Both devices use an I/O sup-
ply from 1.8V to 3.3V. These devices are available in
a 64-pin TQFP package (10mm x 10mm) and a 56-pin
TQFN package (8mm x 8mm x 0.75mm) with an exposed
pad. Electrical performance is guaranteed over the
-40NC to +105NC automotive temperature range.
