Bt856

The Bt856/7 is designed specifically for video systems requiring the generation of 525-line (NTSC/PALM) or 625-line (PALB, D, G, H, I, N, N-Argentina) composite or Y/C (S-video) signals.

The Bt856 and Bt857 are functionally identical, with the exception that Bt857 can output the Macrovision anticopy algorithm.

Horizontal sync (HSYNC*) and vertical sync (VSYNC*) Bt856 may be configured as inputs (slave mode) or outputs (master mode). BLANK* is an input and may be externally controlled.

24-bit linear or gamma-corrected RGB data of Bt856 or 4:2:2 YCrCb data may be input. The rise and fall times of sync, the burst envelope, and closed caption data are internally controlled.

Analog luminance (Y) and chrominance (C) information is available on the Y and C outputs for interfacing to S-video equipment. The composite analog video signal of Bt856 is output simultaneously onto two analog outputs. Bt856 allows one output to provide baseband composite video and another output to drive an RF modulator. Analog RGB is available to support the European SCART/PeriTV interf
