MAX9259/MAX9260
Gigabit Multimedia Serial Link with Spread
Spectrum and Full-Duplex Control Channel
General Description
The MAX9259 serializer pairs with the MAX9260 deseri-
alizer for joint transmission of high-speed video, audio,
and control data.
The MAX9259/MAX9260 operate up to 3.125Gbps for a
15m shielded twisted-pair (STP) cable. 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 embedded audio channel supports I2S up to 32 bits
per sample and at a 192kHz sample rate. The embed-
ded control channel forms a full-duplex, differential
100kbps to 1Mbps UART link between the serializer and
deserializer. The host electronic control unit (ECU) or
microcontroller (FC) resides either on the MAX9259 or on
the MAX9260. In addition, the control channel enables
ECU/FC control of peripherals in the remote side of the
serial link through I2C/UART.
Preemphasis and channel equalization extend the link
length and enhance the link reliability. Spread spectrum
is available to reduce EMI on the serial and parallel out-
put 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/QFND package (8mm x 8mm x 0.75mm) with an
exposed pad. Electrical performance is guaranteed over
the -40NC to +105NC automotive temperature range.
