MAX9653AUB+

Video Amps And Modules Overview

The MAX9653AUB+ is a triple-channel, high-definition video-filter amplifier designed for YPbPr component video signals. It operates from a single 3.3V supply with a quiescent current of 28.9mA to 45mA per device (9.5mA/channel). The unit features a fixed HD lowpass filter with a ±1dB passband up to 42MHz and 50dB attenuation at 109MHz. Inputs are AC-coupled with sync-tip and keyed clamps. The output buffer provides a gain of 2V/V and drives standard back-terminated 75Ω loads. It includes an active-low shutdown mode reducing current to 12µA.

Video Amps And Modules Feature Summary

• Triple-channel architecture optimized for YPbPr component video processing
• Fixed high-definition reconstruction filter ensuring signal integrity
• Integrated input clamping circuits for DC level restoration
• Low-power shutdown capability for standby applications

Video Amps And Modules Applications

• Set-top boxes with analog high-definition outputs
• Portable devices requiring low standby power consumption
• SCART set-top boxes routing HD YPbPr signals

Video Amps And Modules Procurement Notes

Verify the specific suffix 'AUB+' corresponds to the 10-pin µMAX package with shutdown functionality. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the design supports the required 3.3V single-supply operation and accommodates the specified automotive temperature range limits during procurement planning.

Video Amps And Modules Selection Notes

Select this component when a fixed high-definition passband is required without standard-definition switching capabilities. It is suitable for designs needing shutdown control to minimize power consumption in portable or standby modes. Verify that the application utilizes YPbPr inputs rather than RGB or composite formats.

Video Amps And Modules Part Context

This device belongs to the MAX9652/MAX9653/MAX9654 family of 3.3V HD/SD triple-channel filter amplifiers. Unlike the MAX9652 which lacks shutdown, or the MAX9654 which offers selectable SD/HD filters, the MAX9653 provides a dedicated high-definition filter path combined with power-down management for efficient system integration.

Video Amps And Modules FAQ

How does the MAX9653 handle input DC levels?

The inputs must be AC-coupled. The YIN pin uses a sync-tip clamp, while PBIN and PRIN use keyed clamps to set the appropriate DC bias levels.

What is the function of the SHDN pin?

The SHDN pin controls the shutdown mode. Pulling it low reduces quiescent current to typically 12µA and places outputs in a high-impedance state.
