ISL59833IAZ-T7 is a Revolution™ low-power, single-supply video line driver designed to drive low- or high impedance twisted pair cables used in video applications. It is a video amp and module belonging to a linear amplifier family. The video line driver consists of an RF pre-amp, a wide bandwidth video driver amplifier, an integrated peaking amplifier and an output DAC for digital attenuation control. It also features a high linearity pHEMT process and a differential signal path, which provides a low deep null depth and excellent image-reject performance.

The ISL59833IAZ-T7 applications include:

• Video on Demand and CATV systems

• In-Home distribution systems

• DC coupled consumer digital video products

• Video amplifiers and video switchers

• Component video applications such as RGBHV

The working principle of ISL59833IAZ-T7 is as follows:

The signal path of this device is based on differential signal path structures, which means that two outputs are used to transmit the signals. The signals can be of different phase and amplitude. The differential signals reduce cross-coupling interference caused by adjacent video channels and provide high rejection of noise. The differential signal path also provides a low deep null depth, which ensures the necessary signal clarity for today’s digital signals.

The signal is first amplified by a low-noise preamplifier before it is amplified by a wide-bandwidth video driver amplifier. The signal is then further shaped and shaped by an integrated peaking amplifier and an output digital-to-analog converter (DAC) for digital attenuation control. This design feature eliminates the need for a manual control to locate the zero-cross threshold, which increases the flexibility and accuracy in controlling the output level.

ISL59833IAZ-T7 also uses a high linearity pHEMT process to ensure high performance and wide operating temperature range. The wide temperature range allows this device to function reliably in extreme operating environments and is particularly useful in hostile environments and hot environment.

This video line driver can be used with confidence in a variety of video amplifier, video switcher and component video applications. ISL59833IAZ-T7 is a reliable, cost-effective and user-friendly solution that guarantees high-quality video images.
