The MAX9270 deserializer uses Maxim's gigabit multimedia serial link (GMSL) technology. The device functions the same as the MAX9260 deserializer without an output enable (ENABLE) pin. Outputs are enabled or disabled by a register bit. The deserializer pairs with any GMSL serializer to form a complete digital serial link for joint transmission of high-speed video, audio, and control data. The deserializer accepts 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, differential 100kbps to 1Mbps UART link between the serializer and deserializer. The host electronic control unit (E
The MAX9270 is a gigabit multimedia deserializer that pairs with any GMSL serializer to form a complete digital link for high‑speed video, audio and control data. It supports up to 2.5 Gbps payload over 15 m shielded twisted‑pair cable and offers programmable 24‑bit or 32‑bit parallel output buses.
The device is supplied in a 56‑pin TQFN package (8 mm × 8 mm × 0.75 mm) with an exposed pad, operates from a 3.3 V core supply and 1.8 V‑3.3 V I/O supply, and is qualified for automotive temperature ranges from –40 °C to +105 °C. Electrical specifications, pin descriptions, functional diagrams and register tables are provided.
