NJM2296D#

Video Processing Overview

The NJM2296D is a 5-input, 3-output video switch IC manufactured by Nisshinbo Micro Devices Inc. It operates on dual supply voltages ranging from ±4.0V to ±6.5V with a typical operating current of ±31mA at ±5V. The device features an internal 6dB amplifier and a 75Ω driver, designed for audio equipment such as AV amplifiers and receivers. It supports switching between five input signals (Vin1-Vin5) to three outputs (Vout1-Vout3) using control pins SW1-SW5. Key electrical characteristics include a voltage gain of 6.3dB typ., crosstalk of -65dB typ., and differential gain/phase of 0.2% / 0.2deg typ. Operating temperature range is -20°C to +75°C.

Video Processing Procurement Notes

Verify the specific package type required, as the datasheet lists both DIP16 and DMP16 options. Confirm that the design accommodates dual power supplies within the ±4.0V to ±6.5V range. Ensure control logic levels align with the specified high and low switching voltages. Check for end-of-life status or obsolescence notices before finalizing procurement plans.

Video Processing Selection Notes

Select this component when a multi-channel video switching solution with integrated buffering and amplification is needed. It is suitable for designs requiring low crosstalk and minimal differential distortion. Consider the available packages (DIP16 or DMP16) based on board space and mounting requirements. Verify compatibility with standard 1Vpp video signal levels.

Video Processing Part Context

The NJM2296 belongs to Nisshinbo Micro Devices' lineup of video interface ICs. It is part of a series designed for consumer audio-visual applications. The 'D' suffix typically denotes the DIP16 package variant, while 'M' denotes DMP16. This family focuses on providing complete video switching solutions with built-in drivers to simplify circuit design.

Video Processing Replacement Considerations

Check for direct pin-compatible alternatives if the DIP16 package is unavailable. Review specifications for similar 5x3 video switches from other manufacturers to ensure functional equivalence in terms of gain, bandwidth, and power consumption.

Video Processing FAQ

What is the maximum supply voltage for the NJM2296?

The absolute maximum rating for the supply voltage (V+/V-) is ±7V.

How does the mute function work?

The mute function is controlled by the SW1-SW5 pins. Specific combinations of these control signals can force the outputs to a muted state, blocking the video signal.

What is the typical crosstalk performance?

The typical input crosstalk is -65dB, measured at 4.43MHz with a 1Vpp input signal.
