Video Separator IC NTSC, PAL, SECAM 8-PDIP Package # LM1881N/NOPB Engineering Specifications **General Description** The LM1881N/NOPB is a precision video synchronization separator integrated circuit manufactured by Texas Instruments. It is designed to extract timing information from composite video signals and generate synchronization outputs required for video processing, display control, video capture, and television signal applications. The device separates composite sync, vertical sync, burst or back-porch timing, and odd/even field information from standard analog video formats. It operates with both monochrome and color composite video signals and is commonly used in video synchronization systems, frame grabbers, video overlays, video switching equipment, and display synchronization circuits. The integrated circuit simplifies video timing recovery by eliminating the need for complex discrete-component sync separation circuits. Its low-power bipolar architecture provides reliable operation across a wide range of video applications while maintaining accurate synchronization detection. **Engineering Specifications** **Manufacturer:** Texas Instruments **Manufacturer Part Number:** LM1881N/NOPB **Component Type:** Video synchronization separator integrated circuit **Function:** Composite video sync extraction and timing separation **Technology:** Bipolar analog integrated circuit **Video Signal Compatibility:** Composite video input **Supported Video Formats:** NTSC, PAL and SECAM composite video systems **Input Signal Type:** Composite video **Composite Sync Output:** Available **Vertical Sync Output:** Available **Burst or Back-Porch Output:** Available **Odd/Even Field Output:** Available **Synchronization Detection:** Automatic extraction of video timing signals **Power Supply Configuration:** Single-supply operation **Supply Voltage Range:** Wide operating voltage range suitable for video processing systems **Power Consumption:** Low-power operation **Output Configuration:** TTL and CMOS compatible synchronization outputs **Input Coupling:** AC-coupled composite video input **Noise Immunity:** High immunity to video signal disturbances and noise **Signal Processing Capability:** Composite sync, vertical sync and field identification extraction **Applications Compatibility:** Video displays, frame grabbers, video processors, video switching systems and synchronization controllers **Operating Temperature Range:** Commercial temperature range **Package Type:** Plastic dual in-line package **Package Configuration:** Through-hole mounting package **Pin Configuration:** Standard DIP package layout **Mounting Style:** Through-hole **Environmental Compliance:** Lead-free and RoHS compliant NOPB version **Reliability Features:** Stable synchronization extraction and accurate timing recovery **Typical Applications** Video synchronization circuits Video capture equipment Frame grabber systems Television signal processing Video overlay generators Video switching equipment Security and surveillance video systems Display synchronization controllers Industrial video monitoring equipment Embedded video processing systems #LM1881N #LM1881NNOPB #TexasInstruments #VideoSyncSeparator #CompositeVideo #VideoProcessing #EmbeddedSystems #SignalProcessing #FrameGrabber #VideoElectronics #AnalogIC #ElectronicComponents #EngineeringSpecifications #VideoSynchronization
