MAX9270
Gigabit Multimedia Deserializer with Spread Spectrum and Full-Duplex Control Channel
Single-Link Deserializer with Integrated Control Channel Is Ideal for Digital Video Applications
|
Status
Active: In Production.
Description
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 (active-low 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 × 768), or dual-view WVGA (2 × 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 (ECU) or microcontroller (µC) resides either on the serializer (for video display) or the deserializer (for image sensing). In addition, the control channel enables ECU/µC 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 channel equalizer extends the link length and enhances the link reliability. Spread spectrum is available to reduce EMI on the parallel output data signals. The differential link complies with the ISO 10605 and IEC 61000-4-2 ESD-protection standards.
This device uses a 3.3V core supply and a 1.8V to 3.3V I/O supply. The device is available in a 56-pin TQFN 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.
