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.
The XD1881 is a niche, hard-to-find video sync separator with little to no authorized-distributor stock in many regions. Pacific Component Xchange specializes in sourcing scarce and end-of-availability power-management and interface ICs like the XD1881. Submit an RFQ and our team will hunt down authentic, verified inventory, confirm date codes and packaging, and quote competitive pricing with global shipping. Every part is screened for authenticity to protect your build against counterfeits. Request a quote today and let Pacific Component Xchange secure your XD1881 supply.
The XD1881 is a video sync separator IC from Xinluda in a DIP-8 package. It extracts composite sync, vertical sync, burst/back-porch timing and odd/even field information from standard negative-sync NTSC, PAL and SECAM composite video signals.
They are the same Xinluda video sync separator in different packages. The XD1881 is the DIP-8 through-hole version and the XL1881 is the SOP-8 surface-mount version, with the same function and signal outputs.
The XD1881 is functionally comparable to the classic LM1881 video sync separator, offering the same core outputs (composite sync, vertical sync, burst-gate/back-porch, and odd/even field) in an 8-pin DIP. Always confirm pinout and electrical parameters against the datasheet for your specific design.
It accepts AC-coupled composite video with an amplitude of 0.5 V to 2 V peak-to-peak and presents an input resistance greater than 10 ku03a9. The device runs from a single 5 V to 12 V supply.
The XD1881 is supplied in an 8-pin DIP-8 through-hole package. A function-equivalent SOP-8 surface-mount variant is offered as the XL1881.
The XD1881 is a hard-to-find part with limited authorized-distributor availability. Pacific Component Xchange sources scarce video and power-management ICs on a Request-For-Quote basis. Submit an RFQ and our team will locate verified, authentic inventory and provide a quote with global shipping.
