DIY miniature LM1881 Sync Cleaner PCBs with 0805 surface-mount parts. Small format, designed to fit in tight areas like SCART plugs. Can be populated to support 75 ohm or TTL output.
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 unassembled kits include:
470Ω and 75Ω Resistor
.1uf Capacitor (x2)
LM1881 available separately in SOIC format
