Gigabit Multimedia Serial Link with Spread Spectrum and Full-Duplex Control Channel

Single-Link Serializer/Deserializer Chipset with Integrated Control Channel Is Ideal for Digital Video Applications

Please check latest availability status for a specific part variant.


The MAX9259 serializer pairs with the MAX9260 deserializer 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 embedded 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 (µC) resides either on the MAX9259 or on the MAX9260. In addition, the control channel enables ECU/µC 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 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 supply 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 -40°C to +105°C automotive temperature range.
