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 ADV7391.
External HS, VS, and FIELD signals provide timing references
for LCD controllers and other video 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 1.0 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 Â±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
(I2CÂ® compatible) and is fabricated in a 1.8 V 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. The 64-lead
LQFP package is pin compatible with the ADV7181C.
1 The 48-Lead LQFP, 40-lead LFCSP, and 32-lead LFCSP use one pin to output
VS or FIELD.
