AK8851

www.DataSheet4U.com ASAHI KASEI [AK8851] Preliminary AK8851 NTSC/PAL/SECAM Digital Video Decoder General Description The AK8851 is an integrated chip that decodes NTSC, PAL, SECAM composite and S Video signals.. The digital output of the AK8851 is in Y, Cb, Cr signal format which compliances with ITU-R BT.601 and ITU-R BT.656* specifications. An internally generated pixel clock is synchronized with an input signal. The clock rate is 27 MHz. When Closed Caption, VBID or WSS information are encoded on input Video signal, they are externally accessible. Features NTSC-M, NTSC-4.43/PAL-B, D, G, H, I, N, Nc, M, 60/SECAM Composite signals and S Video signal decoding function On-chip dual 10 Bit ADCs (27 MHz operation) Built-in PLLs for input-signal-synchronized clock generation (Line-locked PLL and Frame-locked PLL) On-chip Programmable Gain Amp (PGA), ranging from 0 dB to 12 dB Auto Color Control (ACC) Auto Gain Control (AGC) Automatic input signal distinction function Adaptive 3-/5-line (NTSC/PAL) YC Separation Phase compensation function for PAL signal decoding ITU-R BT.656 format output (4:2:2 8 Bit parallel output with EAV / SAV)/ 16-Bit output is also available NTSC Closed Caption signal decoding function VBID (CGM-A) Program condition decoding function (CRCC decode) WSS Program condition decoding function VBI slicer function Macrovision Certification Power down function 6 – channel Analog inputs I2C Control 3.3 V +/- 10 % CMOS 100...
