Product details
Overview
MAX9264GCB/V+T from Maxim Integrated is an automotive-grade HDCP-enabled GMSL deserializer that receives encrypted high-speed serial video/audio over coax or STP, reconstructs parallel RGB/YUV up to 104MHz pixel clock, and outputs I2S audio with 192kHz/32-bit support. It operates from 3.3V core supply, features programmable equalization for 15m cable drive, and targets infotainment display interfaces in vehicles.
For engineers reviewing the MAX9264GCB/V+T datasheet, MAX9264GCB/V+T pinout, MAX9264GCB/V+T application, or MAX9264GCB/V+T equivalent, key selection criteria include HDCP 1.4 compliance, 3.12Gbps serial link rate, 64-pin TQFP-EP package with exposed pad, -40°C to +105°C operation, and compatibility with MAX9263/MAX9271 serializers in automotive camera/display links.
Technical Context
The MAX9264GCB/V+T implements a CML-based serial receiver with adaptive channel equalization (up to 10.7dB) and bypassable input PLL for jitter attenuation. Its reverse control channel supports full-duplex UART/I2C at 9.6kbps–1Mbps between serializer and deserializer, enabling remote peripheral control including backlight and touch.
It decodes HDCP-encrypted video streams, reconstructs parallel data with configurable bus width (24-/32-bit), and delivers synchronized I2S audio with programmable WS/SCK timing. Power management includes sleep mode (80–230µA) and power-down (<156µA), meeting ASIL-B functional safety readiness requirements for automotive systems.

FAQ
What is the maximum cable length supported by the MAX9264GCB/V+T at full 3.12Gbps data rate?
The MAX9264GCB/V+T supports up to 15 meters of shielded twisted-pair (STP) cable at 3.12Gbps with optimal preemphasis/equalization settings, maintaining BER <10⁻⁹. Performance depends on cable quality and noise environment; typical automotive coax installations achieve 10–12m reliably. The device's programmable equalizer compensates for frequency-dependent loss without external components.
Does the MAX9264GCB/V+T require an external HDCP key storage device?
No, the MAX9264GCB/V+T integrates HDCP 1.4 authentication and encryption engines internally. It performs all cryptographic operations-including key exchange, session key generation, and stream ciphering-without external secure memory or co-processors. Keys are stored in tamper-resistant on-chip ROM, satisfying automotive OEM content protection requirements.
Can the MAX9264GCB/V+T operate with a 1.8V I/O supply voltage?
Yes, the MAX9264GCB/V+T supports IOVDD from 1.7V to 3.6V, including 1.8V. All parallel data outputs (DOUT[0:28]), I2S signals (WS/SCK/SD), and control I/O (TX/SCL, RX/SDA) are fully compatible with 1.8V logic families when IOVDD = 1.8V, provided DVDD/AVDD remain at 3.0–3.6V as specified.
How does the MAX9264GCB/V+T handle synchronization between video and audio streams?
The MAX9264GCB/V+T maintains strict audio-video synchronization by deriving I2S timing (WS, SCK) directly from the recovered PCLKOUT domain. Audio skew relative to video is bounded at 3–4 × tWS, ensuring lip-sync accuracy within ±1 frame at 192kHz. Internal phase alignment circuitry locks audio edges to video pixel boundaries, eliminating software-level resampling.
Is the MAX9264GCB/V+T pin-compatible with earlier MAX9259/MAX9260 devices?
No, the MAX9264GCB/V+T is not pin-compatible with MAX9259/MAX9260. It uses a distinct 64-pin TQFP layout with different pin assignments for PCLKOUT, DOUT bus, and control signals. Migration requires PCB redesign. However, it shares functional compatibility with MAX9263/MAX9271 serializers in the same GMSL ecosystem.
