XD1881 – Video Sync Separator – Xinluda

The Xinluda XD1881 is a DIP-8 video sync separator IC that extracts composite sync, vertical sync, burst/back-porch and odd/even field timing from NTSC, PAL and SECAM video signals. It is the through-hole counterpart of the SOP-8 XL1881 and is functionally comparable to the classic LM1881.

The Xinluda XD1881 is a monolithic video sync separator supplied in an 8-pin through-hole DIP-8 package. It recovers timing information from standard negative-going-sync composite video, making it a drop-in style alternative to the well-known LM1881 sync separator. The XD1881 (DIP-8) and the XL1881 (SOP-8) are the two package variants of the same Xinluda sync-separator die, so designers can choose surface-mount or through-hole assembly while keeping identical function.

The device accepts AC-coupled composite video and produces composite sync, a vertical sync pulse, a burst-gate / back-porch clamp pulse, and an odd/even (parity) field output, giving downstream logic everything it needs to lock to the incoming raster.
