4.4.2 CRT Support
CRT support is provided on connector J3 via the S1D13506 embedded RAMDAC. An
external current reference is implemented to provide the necessary RAMDAC output gain.
The reference current (IREF) should be set to 4.6mA using jumper JP7.
Note
When IREF is set to 4.6mA, the DAC Output Select bit (REG[05Bh] bit 3) must be set
to 1.
CRT output is not available when TV output is enabled.
4.4.3 TV Support
The S1D13506 supports PAL or NTSC TV output. Composite Video is available on
connector J2 and S-Video is available on connector J4. An external current reference is
implemented to provide the necessary RAMDAC output gain. The reference current should
be set to 9.2mA using jumper JP7.
TV output is not available when CRT output is enabled. PAL and NTSC modes cannot be
enabled at the same time.
