30/50MHz 8-BIT CMOS VIDEO DAC
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 75Ω load, or alternatively to produce RS-170 video signals across a singly-terminated 75Ω 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 ±1LSB over the full operating temperature range.
