EVAL-ADV7180LQEBZ: 10-Bit, 4× Oversampling SDTV Video Decoder
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 the ADV7179. 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 video signal peak-to-peak range to 1.0 V. Alternatively, these can be bypassed for manual settings.
The line-locked clock output allows the output data rate, timing signals, 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. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. A 40-lead, RoHS-compliant LFCSP package option makes the decoder ideal for space-constrained portable applications. A 64-lead LQFP package is also available (pin compatible with the ADV7181C).
