Overview
The DAC-104 is a high quality standard definition digital to analog converter for converting 525/625
4:2:2 SDI signals to analog Composite, Y/C and Component signals (YPbPr or RGB). The DAC-104
auto-detects the line input standard and outputs the corresponding NTSC or PAL standard. The user
can configure the default PAL outputs to be PAL-B/D/G/H/I, PAL N or PAL 60 and NSTC M or N.
Pedestal selection can be enabled or disabled for NTSC operation.
The DAC-104 can be externally configured to three different analog output configurations: all
Composite, dual Composite with Y/C or Composite with Component. The DAC-104 supports four
different Component output modes: BetaCam™, MII™, SMPTE/N10 and RGB. The encoding
process is 10-bit with sample up-conversion from 4:2:2 to 8:8:8 (2x output mode) or 16:16:16 (4x
output mode). Full user digital processing (proc.) controls are available to the end user for adjusting
