Product details
Overview
MAX9260GCB/V+T from Maxim Integrated is a gigabit multimedia deserializer for automotive serial video links, supporting up to 3.125Gbps over shielded twisted-pair (STP), XGA (1280×768) or dual-WVGA display resolution, embedded 192kHz/32-bit I²S audio, and full-duplex 100kbps–1Mbps UART control channel. It operates from 3.0V–3.6V AVDD/DVDD and 1.7V–3.6V IOVDD across –40°C to +105°C.
For engineers reviewing the MAX9260GCB/V+T datasheet, MAX9260GCB/V+T pinout, MAX9260GCB/V+T application, or MAX9260GCB/V+T equivalent, key selection criteria include STP cable reach (15m at full speed), AEC-Q100 qualification, spread-spectrum EMI reduction, differential input ESD robustness (±8kV HBM on IN+/IN−), and integrated line-fault monitoring via LMN0/LMN1 pins.
Technical Context
The MAX9260GCB/V+T functions as the deserializer in a paired MAX9259/MAX9260 Gigabit Multimedia Serial Link, receiving high-speed serialized video/audio/control data and reconstructing parallel RGB/YUV outputs with synchronous PCLKOUT. Its reverse control channel uses differential IN+/IN− inputs to receive UART/I²C commands from the serializer side.
It implements programmable equalization (EQS pin), supports 6.25MHz–104MHz pixel clock output (PCLKOUT), delivers 24- or 32-bit parallel DOUT[0:28] with configurable edge timing, and integrates built-in PRBS BER testing, lock detection (LOCK pin), and interrupt forwarding (INT pin) for system-level diagnostics and host coordination.

Pinout & Package
MAX9260GCB/V+T is housed in a 64-pin TQFP package (10mm × 10mm × 1mm) with exposed pad (EP) connected internally to AGND and GND, requiring external connection to the analog ground plane for optimal thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN− | Differential serial data input | Accepts CML-level serialized stream from MAX9259; threshold ±40mV to ±90mV peak; common-mode range 1.0V–1.6V. |

| DOUT0–DOUT28 | Parallel video/audio/data outputs | 24- or 32-bit parallel bus (RGB + SYNC + optional extras); CMOS outputs with 0.2V/0.3V VOL at 2mA. |
| ENABLE | Active-low output enable | Tri-states all parallel outputs (DOUT_, SD, WS, SCK, PCLKOUT) when high - enables shared-bus architectures. |
| LOCK | Link lock status indicator | Open-drain output asserted low when serial link achieves bit lock and frame synchronization. |
| RX/SDA, TX/SCL | I²C/UART bidirectional I/O | Supports master-side I²C or UART communication with host MCU; internal 30kΩ pullups to IOVDD. |
| LMN0, LMN1 | Line fault monitor inputs | Detect short-to-battery, short-to-ground, or open-circuit conditions on STP cable; thresholds defined per Figure 3. |
| ERR | Error flag output | Open-drain signal indicating CRC error, framing error, or invalid control packet reception. |
Key Features

|---|---|
| Spread-spectrum serial output | Programmable 0.5%, 2%, or 4% modulation depth reduces peak EMI by >10dB, easing EMC compliance without shielding. |
| Integrated PRBS BER tester | Enables real-time link integrity verification without external test equipment - critical for production line validation and field diagnostics. |
| Reverse control channel | Full-duplex differential UART over same STP pair eliminates need for separate control wiring, reducing harness cost and weight. |

FAQ
What is the primary function of the MAX9260GCB/V+T in a serial video link?
The MAX9260GCB/V+T serves as the deserializer in a bidirectional MAX9259/MAX9260 Gigabit Multimedia Serial Link. It receives high-speed serialized video, audio, and control data over a differential STP cable, reconstructs parallel RGB/YUV video outputs with synchronous PCLKOUT, and processes reverse-channel UART/I²C commands. Its design enables compact, EMI-robust video transport in automotive environments where cable length and reliability are critical.
Does the MAX9260GCB/V+T support both 24-bit and 32-bit video modes?
Yes, the MAX9260GCB/V+T supports both 24-bit and 32-bit parallel output modes. Bus-width selection is controlled by the BWS pin: BWS = low configures DOUT0–DOUT20 for RGB + SYNC (24-bit mode), while BWS = high enables DOUT0–DOUT28 for extended data (32-bit mode). The device maintains full timing compliance and jitter performance in both configurations, with PCLKOUT ranging from 6.25MHz to 104MHz accordingly.
How does the MAX9260GCB/V+T handle electromagnetic interference (EMI) in automotive applications?
The MAX9260GCB/V+T reduces EMI through programmable spread-spectrum modulation (0.5%, 2%, or 4%) on its serial input path, lowering peak spectral energy by >10dB. Its differential CML receiver (IN+/IN−) provides inherent common-mode noise rejection, and it meets ISO 10605 (±10kV contact) and IEC 61000-4-2 (±8kV contact) ESD standards. These features collectively minimize radiated emissions and improve immunity in electrically noisy vehicle cabins and harnesses.
Can the MAX9260GCB/V+T be used without the companion MAX9259 serializer?
No - the MAX9260GCB/V+T is designed exclusively as the deserializer partner to the MAX9259 serializer. It relies on the MAX9259's specific serialization protocol, embedded clock recovery, and control-channel framing. While the MAX9260GCB/V+T can operate in standalone test modes (e.g., PRBS loopback), functional video/audio transport requires the matched MAX9259/MAX9260 pair. Substituting with non-Maxim serializers is not supported.
What diagnostic capabilities does the MAX9260GCB/V+T provide for system integration?
The MAX9260GCB/V+T provides multiple hardware-level diagnostics: LOCK pin indicates serial link bit/frame lock; ERR pin flags CRC or framing errors; INT pin forwards interrupts from the remote MAX9259 side; LMN0/LMN1 inputs detect STP cable faults (short-to-battery, short-to-ground, open); and the integrated PRBS BER tester enables real-time link quality measurement. All signals are accessible without software overhead, supporting ASIL-B diagnostic coverage in automotive systems.
