Ready for high-def broadcast systems, the LMH1981 sync separator makes its mark by claiming the best jitter performance available, allowing users to extract signals without extra filtering and jitter-cleaning stages. Based on input-referred jitter testing using high-def inputs, it promises up to 30% improvement in horizontal-sync output jitter over comparable devices. The chip performs all sync separation for NTSC, PAL, and SECAM. Other features include: all timing outputs including horizontal, vertical, composite, odd/even field, and burst/back porch clamp; automatic format detection; bi- and tri-level sync inputs; and 50% slicing to handle signals varying in amplitude, offset, and noise. The device operates on voltages from 3.3V to 5V and is compatible with Macrovision's video copy protection system. Sampling now in a TSSOP-14, price is $3.79 each/1,000.
