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 STRDAC 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 RSET external resistor. Pull up resistors have been added to tie all unused control inputs into their inactive (High) states.
