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) 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.

Data Sheet
ADV7180
INTRODUCTION
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 simple digital output interface connects gluelessly to a wide
range of MPEG encoders, codecs, mobile video processors, and
Analog Devices digital video encoders, such as the ADV7391.
External HS, VS, and FIELD signals provide timing references
for LCD controllers and other video ASICs that do not support the
ITU-R BT.656 interface standard. The different package options
available for the ADV7180 are shown in Table 2.
ANALOG FRONT END
The ADV7180 analog front end comprises a single high speed,
10-bit analog-to-digital converter (ADC) that digitizes the
analog video signal before applying it to the standard definition
processor. The analog front end employs differential channels to
the ADC to ensure high performance in mixed-signal applications.
The front end also includes a 3-channel input mux that enables
multiple composite video signals to be applied to the ADV7180.
Current clamps are positioned in front of the ADC to ensure
that the video signal remains within the range of the converter.
A resistor divider network is required before each analog input
channel to ensure that the input signal is kept within the range
of the ADC (see Figure 29). Fine clamping of the video signal
is performed downstream by digital fine clamping within the
ADV7180.
Table 1 shows the three ADC clocking rates that are determined by
the video input format to be processed—that is, INSEL[3:0].
These clock rates ensure 4× oversampling per channel for CVBS
mode and 2× oversampling per channel for Y/C and YPrPb modes.

2 See INSEL[3:0] in Table 107 for the mandatory write for Y/C (S-Video) mode.
STANDARD DEFINITION PROCESSOR
The ADV7180 is capable of decoding a large selection of baseband
video signals in composite, S-Video, and component formats.
The video standards supported by the video processor include
PAL B/D/I/G/H, PAL 60, PAL M, PAL N, PAL Nc, NTSC M/J,
NTSC 4.43, and SECAM B/D/G/K/L. The ADV7180 can auto-
matically detect the video standard and process it accordingly.
The ADV7180 has a five-line, superadaptive, 2D comb filter
that gives superior chrominance and luminance separation
when decoding a composite video signal. This highly adaptive filter
automatically adjusts its processing mode according to the video
standard and signal quality without requiring user intervention.
Video user controls such as brightness, contrast, saturation, and
hue are also available with the ADV7180.
The ADV7180 implements a patented ADLLT™ algorithm to
track varying video line lengths from sources such as a VCR.
ADLLT enables the ADV7180 to track and decode poor quality
video sources such as VCRs and noisy sources from tuner outputs,
VCD players, and camcorders. The ADV7180 contains a chroma
transient improvement (CTI) processor that sharpens the edge
rate of chroma transitions, resulting in sharper vertical transitions.
The video processor can process a variety of VBI data services,
such as closed captioning (CCAP), wide screen signaling (WSS),
copy generation management system (CGMS), EDTV, Gemstar®
1×/2×, and extended data service (XDS). Teletext data slicing
for world standard teletext (WST), along with program delivery
control (PDC) and video programming service (VPS), are
provided. Data is transmitted via the 8-bit video output port as
ancillary data packets (ANC). The ADV7180 is fully Macrovision®
certified; detection circuitry enables Type I, Type II, and Type III
protection levels to be identified and reported to the user. The
decoder is also fully robust to all Macrovision signal inputs.
