Introduction
The TVP5146M2 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 TVP5146M2 decoder supports the
analog-to-digital (A/D) conversion of component RGB and 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
four 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 RGB, YPbPr, CVBS,
or S-video video inputs.
Component, composite, or S-video signals are sampled at 2
× the ITU-R BT.601 clock frequency, line-locked,
and are then decimated to the 1
× pixel rate. CVBS decoding utilizes 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.
A built-in color space converter is applied to decoded component RGB data.
The following output formats can be selected: 20-bit 4:2:2 YCbCr or 10-bit 4:2:2 YCbCr.
The TVP5146M2 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 TVP5146M2 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 TVP5146M2 decoder can pass through the output formatter 2
×
the sampled raw luma data for host-based VBI processing.
The decoder provides the option for concurrent processing of pixel-locked CVBS and RGB/YPbPr input
formats.
The main blocks of the TVP5146M2 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
Fast-switch input for pixel-by-pixel switching between CVBS and YPbPr/RGB component video inputs
(SCART support)
Four 10-bit, 30-MSPS A/D converters with analog preprocessors [clamp and automatic gain control
(AGC)]
Luminance processor
Chrominance processor
Component processor
Clock/timing processor and power-down control
Software-controlled power-saving standby mode
Output formatter
I2C host port interface
VBI data processor
