ADV7180:  10-Bit, 4× Oversampling SDTV Video Decoder

Product Description

The ADV7180 automatically detects and converts standard analog baseband television signals compatible with worldwide NTSC, PAL, and SECAM standards into 4:2:2 component video data compatible with the 8-bit ITU-R BT.656 interface standard.

The simple digital output interface connects gluelessly to a wide range of MPEG encoders, codecs, mobile video processors, and Analog Devices, Inc., digital video encoders, such as theADV7179. External HS, VS, and FIELD signals provide timing references for LCD controllers and other video ASICs, if required.

The accurate 10-bit analog-to-digital conversion provides professional quality video performance for consumer applications with true 8-bit data resolution. Three analog video input channels accept standard composite, S-video, or component video signals, supporting a wide range of consumer video sources. AGC and clamp-restore circuitry allow an input videosignal peak-to-peak range up to 1.0 V. Alternatively, these can be bypassed for manual settings.

The line-locked clock output allows the output data rate, timingsignals, and output clock signals to be synchronous,asynchronous, or line locked even with ±5% line length variation. Output control signals allow glueless interface connections in many applications. The ADV7180 is programmed via a 2-wire, serial, bidirectional port (I2C compatible).

The ADV7180 is fabricated in a 1.8 V CMOS process. Itsmonolithic CMOS construction ensures greater functionality with lower power dissipation. A chip-scale, 40-lead, Pb-free LFCSP package option makes the decoder ideal for space constrained portable applications. A 64-lead LQFP package is also available (pin compatible with ADV7181B).
