MAX9129EUE+

The MAX9129EUE+ is a low-power, 3.3-V, single-channel, high-speed, low-skew, low-jitter, differential-output video data receiver with an integrated cable driver. This device combines low-power complementary metal-oxide semiconductor (CMOS) circuitry with developed on-chip hardware to achieve ultra-wide bandwidth, low skew and jitter, and superior common-mode noise filtering over extended temperature ranges. The MAX9129EUE+’s input driver is designed to accept either a single-ended or differential-ended interface.

The MAX9129EUE+ is well-suited for applications like Blu-ray disc or optical disc recording, wherein high-speed video serial data must be robustly transmitted over long cables or drop cables. This application requires the use of a high-speed data receiver with good electromagnetic compatibility (EMC) and good EMI/RFI performance. The MAX9129EUE+ provides significant advantages in comparison to other devices for this application, including low-skew, maximum jitter of 8 picoseconds (ps) @ 256×F SCART, low-power consumption (4 mW), and its low-voltage (3.3-V) design.

The device features a power-down mode, in which the output data is held low. The MAX9129EUE+ also includes an integrated shutdown control pin which can be used to enable or disable the device, allowing the user to use lower overall power consumption in standby or sleep modes.

Working Principle

The working principle of a MAX9129EUE+ is based on a differential-output video data receiver with an integrated cable driver. In operation, the MAX9129EUE+ accepts either single-ended or differential-ended data input and provides, via the output pins, a low-skew and low-jitter combination of the data inputs in a single-ended or differential format. The device takes advantage of both the natural impedance matching and common-mode noise-cancelling features of a differential data transmission scheme.

The MAX9129EUE+ features three control pins, including a power-down pin, an shutdown pin that allows for low-power consumption in standby mode, and a feedback pin used to establish a reference voltage for the internal circuitry. An internal reference voltage circuit keeps the feedback pin level stable at a predetermined voltage level and is used for power supply rejection (PSR). This stability of the reference voltage enables the device to accurately operate over a wide range of supply voltages.

The MAX9129EUE+ employs a high-speed, low-power architecture in order to maximize its operating speed while minimizing power consumption. The device incorporates a low-noise, high-linearity input stage, a low-power clocked gain stage, and differential-output to single-ended drivers with an integrated ESD protection network. The device is well-suited for applications requiring low-skew, high-bandwidth video data transmission with low EMC emissions.

Conclusion

The MAX9129EUE+ is a single-channel, high-speed, low-skew, low-jitter, differential-output video data receiver with an integrated cable driver. This device combines low-power CMOS circuitry with optimized on-chip hardware and is the ideal choice for applications requiring robust transmission of video serial data over long cables or drop cables. The device is well-suited for applications requiring low-skew, high-bandwidth video data transmission with low EMC emissions, such as Blu-ray disc or optical disc recording. The device also incorporates a power-down mode, a shutdown control pin for lower overall power consumption in standby, and a feedback pin for improved PSR.
