ADV7180

The ADV7180 is a versatile one-chip multiformat video decoder that automatically detects and converts PAL, NTSC, and SECAM standards in the form of composite, S-video, and component video into a digital ITU-R BT.656 format.The typical applications include digital camcorders and PDAs, low-cost SDTV PIP decoder for digital TVs, multichannel DVRs for video security, AV receivers and video transcoding, PCI-/USB-based video capture and TV tuner cards, personal media players and recorders, smartphone/multimedia handsets, in-car/automotive infotainment units and rearview camera/vehicle safety systems.

There are some features of ADV7180 as follows. First is three video input channels with on-chip antialiasing filter. The second is CVBS (composite), Y/C (S-video), and YPrPb (component) video input support. Then is 5-line adaptive comb filters and CTI/DNR video enhancement. Next is 1.0 V analog input signal range. The fifth is full feature VBI data slicer with teletext support (WST). The sixth is power-down mode and ultralow sleep mode current. The last one is integrated AGC with adaptive peak white mode.

What comes next is about the electrical characteristics of ADV7180 at AVDD = 1.71 V to 1.89 V, DVDD = 1.65 V to 2.0 V, DVDDIO = 3.0 V to 3.6 V, PVDD = 1.65 V to 2.0 V, specified at operating temperature range, unless otherwise noted. The minimum VIH (Input High Voltage) is 2 V. The maximum VIL (Input Low Voltage) is 0.8 V. The minimum VIH (Crystal Inputs) is 1.2 V. The maximum VIL (Crystal Inputs) is 0.4 V. The minimum IIN (Input Current) is -10A and the maximum is +10 A. The maximum CIN (Input Capacitance) is 10 pF.
