Product Overview
The BT861KRF is an integrated digital video encoder originally developed by Rockwell/Conexant, now owned by Synaptics. Designed for set-top boxes, video editing gear and industrial monitoring systems, it converts CCIR 601/656 standard 8-bit YCrCb digital signals into composite, S-Video and analog component outputs supporting NTSC, PAL and SECAM. Equipped with 10-bit internal DACs and anti-imaging filters to eliminate dot crawl and sync skew, this IC is packaged in an 80-Pin PQFP, delivering stable analog video conversion for legacy broadcast and multimedia equipment globally.
Core Advantages
Multi-Format Analog Rendering Output
Natively formats incoming digital data into composite, S-video, and component analog feeds simultaneously, providing extensive interface flexibility for video mixing equipment.
Advanced Digital Anti-Imaging Filtration
Incorporates specialized on-chip digital luma and chroma interpolation filters that filter out processing clock harmonics, yielding crisp outlines and clean color definition.
Universal Broadcast Standards Integration
Supports NTSC, PAL and SECAM global broadcast encoding standards, switchable via simple hardware control pin states or internal memory registers to match regional specifications.
Robust Synchronous Clock Controls
Utilizes precision line-locked clock configurations and digital timing generators to secure unwavering horizontal and vertical sync fields over long coaxial connection lines.

Frequently Asked Questions
Q1: Is your currently available stock of the BT861KRF 100% original and genuine?
A: Yes, we guarantee that all BT861KRF video encoders in our inventory are 100% brand-new, factory-original products from Conexant / Synaptics (Formerly Rockwell Semiconductor). Every single component lot passes strict incoming inspection checks and is packed in original anti-static trays or tubes to keep the package leads flat and pristine.
Q2: Can the BT861KRF chip convert digital RGB signals directly into analog television outputs?
A: The primary input format for the BT861KRF is component digital YCrCb data streams matching CCIR 601/656 standards. If your main host controller outputs raw RGB signals, they must first pass through a digital matrix color space conversion block before interfacing with this encoder’s digital input bus lines.
Q3: How does this encoder IC handle switching between international NTSC, PAL and SECAM television formats?
A: Switching between NTSC, PAL and SECAM formats is managed dynamically. Hardware engineers can configure the change by adjusting specific logic voltage levels on external hardware configuration pins, or software developers can modify internal control registers via the I2C serial microprocessor interface during system setup.
Q4: How can our physical engineering group secure the full schematic layout or request tiered volume quotes?
A: Please complete our Quick Inquiry web form found directly on this product page, noting your target quantities and specific project metrics. Our specialized video interface technical support desk will review your submission and reply with full data assets and custom commercial pricing tables within 24 hours.
