ASAHIKASEI [AK8813/14] AK8813/14 NTSC/PAL Digital Video Encoder GENERAL DESCRIPTION The AK8813/14 is low voltage, low power and small packaged Digital Video Encoder. It is suitable for a STB or Digital TV. It converts ITU-R.BT601/656 standard 8- bit parallel data into analog composite video signal, S-video in NTSC and PAL formats. AK8813/14 supports Copy protection, Closed Captioning and Video Blanking ID(CGMS-A) and WSS. These functions are controlled by high-speed I2C Bus interface. FEATURES • NTSC-M, PAL-B,D,G,H,I,M,N encoding. • Simultaneous composite video signal and S-video signal outputs • ITU-R BT.656 4:2:2 8-bit Parallel Input – EAV Decoding • Master/Slave Operation – Digital Field Sync I/O – Digital Vertical/Horizontal Sync I/O • Y filtering • C filtering • Triple 10-bit DACs • I2C Bus Interface (400kHz) • Closed Caption encoding (NTSC: line 21,284-SMPTE PAL: line 22,335-CCIR) • Macrovision Copy Protection Rev. 7.1 * (only AK8814 ) • VBID, CGMS-A(EIAJ CPR-1024) • WSS • On-chip color bar generator • Low power consumption • 2.8V to 3.3V operation CMOS Monolithic • 48pin LQFP Package / 57pin FBGA Package (*Note) This device is protected by U.S. patent numbers 4,631,603, 4,577,216, and 4,819,098, and other intellectual rights.
