Quick solder board for adding YPbPr component video output to the Sharp Famicom Titler. Fits over the PPU pins on the underside of the board for an easy and tidy install. Should theoretically also work for other systems with RGB PPUs, but you’re on your own for those.

BOM is listed on the silkscreen. All passives are 0805.

The color saturation is set by the values selected for the resistors marked A and B. Using 150 ohm for both resistors will yield 50% saturation, matching the colors of the Titler’s stock composite and S-Video output. Using 75 ohm for A and leaving B unpopulated will yield 100% saturation, matching the raw RGB colors from the PPU. Using 100 ohm for A and 300 ohm for B yields 75% saturation for a pleasing middle ground.

Adding 220-1000 uF capacitors inline on the outputs is suggested, but not strictly required. Try it if you experience issues.

A 3D-printable TRRS jack bracket is available in the Github repository.

Adapts the proprietary PlayStation AV multi out to a VGA-style DE15 connector and 3.5mm headphone jack. Switchable between separate sync (RGBHV) or composite sync (RGBS).
