NJM2285V-TE1

Video Processing Overview

The NJM2285V-TE1 is a video switch IC featuring three independent switching circuits, each with two inputs and one output. Two circuits utilize clamp technology to maintain fixed DC levels in video signals. It operates on a supply voltage of 4.75 to 13.0 V, supports a bandwidth frequency feature of 10 MHz (at 2 V P-P input), and achieves crosstalk of -75 dB at 4.43 MHz. The device uses bipolar technology and is housed in a DMP-16 package.

• Integrates three independent switching circuits, each providing two inputs and one output for signal routing.
• Features two internal clamp-type circuits designed to maintain fixed DC levels within video signals during operation.
• Supports wide operating supply voltages ranging from 4.75 V to 13.0 V for flexible power integration.

Video Processing Applications

• Video Cassette Recorders (VCR)
• Video Cameras
• Audio/Video Televisions (AV-TV)
• Video Disk Players

Video Processing Procurement Notes

Verify the exact suffix 'V' against official documentation to confirm the specific package type, as datasheets list multiple options including DIP16, DMP16, and SSOP16. Confirm current availability status directly with Nisshinbo Micro Devices or authorized distributors, as older component series may face discontinuation or limited stock constraints.

Video Processing Selection Notes

Select this component when designing systems requiring simultaneous switching of multiple video channels with precise DC level retention. The integrated clamp functionality makes it suitable for applications where maintaining signal integrity across different video sources is critical. Ensure the design accommodates the required 1 MΩ resistance between input and ground pins for stable clamp operation.

Video Processing Part Context

The NJM2285 belongs to the NJM2285 series of video switch ICs manufactured by Nisshinbo Micro Devices. This series utilizes bipolar technology to provide efficient signal routing for consumer electronics. The component is part of a broader portfolio of analog and video processing solutions aimed at audio and video equipment manufacturers.

Video Processing Replacement Considerations

Consult official substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering similar video switch ICs from other manufacturers.

Video Processing FAQ

Why is external resistance required for the clamp type inputs?

A 1 MΩ resistance must be placed between the INPUT and GND pins for clamp type inputs because minute currents can otherwise cause unstable pin voltages.

What is the specified crosstalk performance at 4.43 MHz?

The typical crosstalk specification is -75 dB when measured at a frequency of 4.43 MHz with a 2 V P-P input signal.
