DIY miniature LM1881 Sync Cleaner PCBs with 0805 surface-mount parts. Small format, designed to fit inside SCART plug heads.
Used in conjunction with an LM1881 IC to extract CSYNC signals from Composite video inputs for use with RGB-capable systems that don't natively output CSYNC.
Sync cleaners are needed for RGB with certain brands of monitors and upscalers that cannot process SYNC signals from Composite video. In some cases, even if the monitor can use Composite video, a sync cleaner circuit will further improve video quality.
These DIY kits include:
.1uf Capacitor (x2)
Optional SOIC LM1881, or no IC if providing your own LM1881
USAGE NOTE: These PCBs can be configured to output TTL or 75 ohm sync. If your equipment is not compatible with TTL sync, please be sure to populate the 470 ohm resistor. To configure for TTL, solder a jumper across the TTL terminals.
