The MAX9259/MAX9260 chipset presents Maxim’s gigabit multimedia serial link (GMSL) technology. It supports joint transmission of high-speed video, audio, and control data. It allows a maximum serial payload data rate of 2.5Gbps for a 15m shielded twisted-pair (STP) cable. It 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, differential 100kbps to 1Mbps UART link.
The MAX9259 serializer and MAX9260 deserializer form a gigabit multimedia serial link (GMSL) for high‑speed video, audio, and control data transmission. The link supports up to 2.5 Gbps payload over a 15 m shielded twisted‑pair cable and offers 24‑bit or 32‑bit parallel interfaces with bus clocks up to 104 MHz or 78 MHz.
Both devices operate from 1.8 V (MAX9259) and 3.3 V (MAX9260) core supplies, are available in 64‑pin TQFP and 56‑pin TQFN packages, and meet automotive temperature specifications of –40 °C to +105 °C. The datasheet includes electrical characteristics, absolute maximum ratings, package information, and ordering details.
