The VP101 is a CMOS 8-bit video DAC designed for
use in high performance, high resolution colour graphics
applications.
The device uses video control inputs (BLANK, SYNC
and REF WHITE) to provide the VP101 with the video
pedestal levels required to generate RS-343A compatible
video signals into a doubly-terminated 75
alternatively to produce RS-170 video signals across a
singly-terminated 75
load.
Data and control inputs are fully pipelined to maintain
synchronisation between the DAC outputs.
The full scale output current is defined by a 1.2V
reference and a single resistor. The reference voltage is
included on-chip in the VP101, but may be supplied
externally if required (see Fig. 2).
Differential and integral linearity errors of the D-A
converters are guaranteed to be a maximum of
the full operating temperature range.
