Example for External Circuit
A. Connect IOUT to a high-impedance video buffer device.
B. Place capacitors and resistors as close as possible to the DM335.
C. Configure the VDAC_CONFIG register in the system control module as follows: DINV = 0, PWD_GBZ = 1,
PWD_VBUFZ = 0, ACCUP_EN = X. See the TMS320DM335 Digital Media System-on-Chip (DMSoC) ARM
Subsystem Reference Guide (literature number SPRUFX7) and the TMS320DM335 Digital Media System-on-Chip
(DMSoC) Video Processing Back End (VPBE) Reference Guide (literature number SPRUFX9) for more information
on VDAC_CONFIG.
