The MV95308 is a CMOS 8-bit, 30MHz Digital to
Analog converter, designed for use in both video graphics
and general digital television applications.
A very low external component count has been
achieved by including the loop amplifier and reference
voltage source on chip.
The device contains a data input register and registered
video controls (BLANK
, REFWHITE, OVERBRT and SYNC).
These control inputs and associated internal circuitry allows
the MV95308 to be used in video graphics systems by
providing the necessary video pedestal levels. The STRD
AC
input allows the video pedestals to be disabled in
conventional DAC applications.
This device is capable of directly driving 75
Ω
lines with
standard RS-343A or RS-170 video levels, using the
appropriate R
SET
external resistor.
Pull up resistors have been added to tie all unused
control inputs into their inactive (High) states.
