CH7055A-BF Description

Short technical summary and product information.

The Chrontel CH7055A-BF is a low-cost, low-power semiconductor device featuring three separate 10-bit video Digital-to-Analog Converters (DACs). It converts digital input signals into analog current outputs at a maximum conversion rate of 200 MHz, based on a current source architecture.

 

This device supports a wide range of input resolutions, up to 1920x1200@75Hz, and includes features like Composite Sync Control input and output, and Sync on Green mode support. The DAC output current range is from 2.0 mA to 36 mA. It operates with IO supply voltages from 1.8V to 3.3V.

 

The CH7055A-BF is fabricated in a CMOS process, ensuring high functionality with low power dissipation. It also includes an advanced Image Enhancement module for contrast and brightness adjustments, controllable via a serial programmable interface. The device is offered in a 40-pin QFN package, suitable for surface mounting.

 

Applications include car entertainment devices, PC video cards, high-resolution image processing, digital video systems, and general-purpose high-speed digital-to-analog conversion.
