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 165 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.
