Like the X-One before it, X-DTV will use Yvo’s VDP video engine but instead of driving a VGA output it will drive a NTSC TV output. We hope to get PAL TV as well but the 35.46895MHz oscillators have proven difficult to get a hold off (If anyone know where we can get them off the shelve without a large MOQ then drop me a comment).
The X-DTV’s specification is:
- XS1-L1 64 internally clocked to 400MHz with 64K RAM.
- 5-bit R-2R Video DAC for driving NTSC
- 2x NES or SNES D-PAD connectors
- SD Card interface
- Stereo PWM audio
- XTAG-2 Interface
- 2x 5-way XLINK for expansion
The latest (not quite complete) PCB is below:
