Introduction
The TVP5147 device is a high-quality, single-chip digital video decoder that digitizes and decodes all popular
baseband analog video formats into digital component video. The TVP5147 decoder supports the
analog-to-digital (A/D) conversion of component YPbPr signals, as well as the A/D conversion and decoding
of NTSC, PAL, and SECAM composite and S-video into component YCbCr. This decoder includes two 10-bit
30-MSPS A/D converters (ADCs). Preceding each ADC in the device, the corresponding analog channel
contains an analog circuit that clamps the input to a reference voltage and applies a programmable gain and
offset. A total of 10 video input terminals can be configured to a combination of YPbPr, CVBS, or S-video video
inputs.
Composite or S-video signals are sampled at 2
× the square-pixel or ITU-R BT.601 clock frequency, line-locked
alignment, and are then decimated to the 1
× pixel rate. CVBS decoding uses five-line adaptive comb filtering
for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap
filter is also available. On CVBS and S-video inputs, the user can control video characteristics such as
contrast, brightness, saturation, and hue via an I2C host port interface. Furthermore, luma peaking
(sharpness) with programmable gain is included, as well as a patented chroma transient improvement (CTI)
circuit.
The following output formats can be selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr.
The TVP5147 decoder generates synchronization, blanking, field, active video window, horizontal and vertical
syncs, clock, genlock (for downstream video encoder synchronization), host CPU interrupt and programmable
logic I/O signals, in addition to digital video outputs.
The TVP5147 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI
data processor (VDP) slices, parses, and performs error checking on teletext, closed caption (CC), and other
VBI data. A built-in FIFO stores up to 11 lines of teletext data, and with proper host port synchronization,
full-screen teletext retrieval is possible. The TVP5147 decoder can pass through the output formatter 2
×
sampled raw luma data for host-based VBI processing.
The main blocks of the TVP5147 decoder include:
Robust sync detection for weak and noisy signals as well as VCR trick modes
Y/C separation by 2-D 5-line adaptive comb or chroma trap filter
Two 10-bit, 30-MSPS A/D converters with analog preprocessors [clamp and automatic gain control
(AGC)]

Luminance processor
Chrominance processor
Clock/timing processor and power-down control
Software-controlled power-saving standby mode
