DESCRIPTION/ORDERING INFORMATION
This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to
track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB
accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation
between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB.
When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. To ensure the
high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor;
the minimum value of the resistor is determined by the current-sourcing capability of the driver.
The TXB0104 is designed so that the OE input circuit is supplied by VCCA.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.

accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation

TVP5146M2
NTSC/PAL/SECAM 4×10-Bit Digital Video Decoder
With Macrovision™ Detection, YPbPr Inputs, 5-Line Comb
Filter, and SCART Support
1.2 Description
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 11-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 ten 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 5-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.
Two 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 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 11-bit 30-MSPS ADCs 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
• Macrovision™ copy protection detection circuit (Type 1, 2, 3, and separate color stripe detection)
• 3.3-V tolerant digital I/O ports
1.3 Applications
• Digital TV
• LCD TV/monitors
• DVD-R
• PVR
• PC video cards
• Video capture/video editing
• Video conferencing
• Automotive
