The ADV7189 is a multiformat SDTV video decoder from Analog Devices, which supports NTSC-(M,N,4.43), PAL-(B/D/G/H/I/M/N) and SECAM formats. The chip integrates three 54MHz, Noise Shaped Video®, 12-bit ADCs, and is driven by a single 27MHz crystal clock. It also uses Line-locked clock compatible (LLC), Adaptive-Digital-Line-Length-Tracking (ADLLT™) and 5-line adaptive comb filters to ensure locking on weak, noisy, unstable video sources (such as VCRs and tuners). In addition, the chip integrates AGC, Macrovision® copy protection detection, CTI and DNR, which can meet the needs of more application scenarios.
