描述

chrontel’s ch7055a is a low-cost, low-power semiconductor device that consists of three separate 10-bit video digital-to-analog converters (dacs), which can convert the digital input signals into analog current outputs at a maximum conversion rate of 200 mhz.

the dacs are based on current source architecture. sync and dac control logic module receives horizontal and vertical sync input, generates composite sync and internal synchronization control signal. the ch7055a has a power-down mode to reduce power consumption as required.

the ch7055a is fabricated in a cmos process that ensures high functionality with low power dissipation. with advanced image enhancement module integrated to achieve the modification of the contrast, brightness, etc, the display quality can be flexible adjusted and optimized through the serial programmable interface.
