NE568 NE568A;SA568A 150MHz Phase-locked Loop

Description: NJM2268 is a dual video 6dB amplifier designed for S-VHS VCRs, high-bandwidth VCRs, and similar applications. One channel features a clamp function that stabilizes the DC level of the video signal, while the other channel operates as a bias type. Additionally, it includes 75 ohm drivers that can connect directly to TV monitors and sag corrective circuits to minimize sag with reduced capacitance. The operating supply voltage ranges from 4.85V to 9V, and it has a bandwidth of 7MHz.

The NJM2268 amplifier is specifically tailored for video signal processing, making it highly suitable for high-quality video applications. The dual-channel configuration allows for simultaneous amplification of two video signals, ensuring versatility in various setups. The clamp function in one channel is particularly beneficial as it automatically adjusts the DC level of the incoming video signal, preventing distortion and maintaining signal integrity. This feature is crucial in applications where consistent video quality is required, such as in professional video editing or broadcasting.

The bias-type channel provides an alternative amplification method, which can be advantageous in scenarios where specific signal characteristics are desired. The integrated 75-ohm drivers facilitate direct connections to television monitors, eliminating the need for additional impedance-matching components, thus simplifying system design and reducing potential signal loss.

The sag corrective circuits are an innovative addition to the NJM2268, designed to counteract sagging effects that can occur in video signals, particularly when using smaller capacitors. This feature enhances the overall performance of the amplifier, ensuring that the output remains stable and clear even under varying load conditions.

Operating within a supply voltage range of 4.85V to 9V allows for flexibility in power supply options, making the NJM2268 suitable for both portable and fixed installations. The bandwidth of 7MHz ensures that the amplifier can handle a wide range of video frequencies, making it ideal for high-resolution video applications. Overall, the NJM2268 is a robust and efficient solution for video amplification needs in modern multimedia systems.NJM2268 is a dual Video 6dB Amplifier with 75 drivers for S-VHS VCRsHI-BAND VCRsetc. One channel has clamp function that fixes DC level of Video signal and another one is bias type.
