Analog Devices Inc. 亚德诺半导体 ADV7180 过采样 SDTV 视频解码器

The simple digital output interface connects to a wide range of MPEG encoders, codecs, mobile video processors, and Analog Devices, Inc., digital video encoders. External HS, VS, and FIELD signals provide timing references for LCD controllers and other videos ASICs if required. 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 1.0V. 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) and is fabricated in a 1.8V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. LFCSP package options make the decoder ideal for space-constrained portable applications.

Analog Devices offers the EVAL-ADV7180LFEBZ for the 40-lead LFCSP ADV7180, EVAL-ADV7180LQEBZ for the 64-lead LQFP ADV7180, and EVAL-ADV7180-32EBZ  for the 40-lead LFCSP ADV7180 to help designers evaluate the features of the ADV7180 video decoders.
