Product Summary

The TW280X includes four high quality NTSC/ PAL video decoders, which convert analog composite to digital component YCbCr for security application. The TW280X contains four 10-bit A/D and proprietary digital gain/clamp controllers and utilizes proprietary techniques for separating luminance & chrominance to reduce both crossluminance and cross-chrominance artifacts.
Four built-in motion detectors can also increase the feature of security system.The high performance dual scalers in each channel offer two differently scaled video
outputs with 54MHz ITU-R BT.656 format for security system design.

Parametrics

VSCALE = [120 / 240] * (2^16 閳?1) = 0x7FFF for 60Hz
VSCALE = [144 / 288] * (2^16 閳?1) = 0x7FFF for 50H
