Description
The TVP5154 device is a 4-channel, low-power, NTSC/PAL/SECAM video decoder. Available in a space-saving 128-pin thin quad flat pack (TQFP) package, each channel of the TVP5154 decoder converts NTSC, PAL, or SECAM video signals to 8-bit ITU-R BT.656 format. Discrete syncs are also available. All four channels of the TVP5154 are independently controllable. The decoders share one crystal for all channels and for all supported standards. The TVP5154 can be programmed using a single inter-integrated circuit (I2C) serial interface. The decoder uses a 1.8-V supply for its analog and digital supplies, and a 3.3-V supply for its I/O. The optimized architecture of the TVP5154 decoder allows for low power consumption. The decoder consumes less than 720 mW of power in typical operation. Each channel of the TVP5154 is an independent video decoder with a programmable polymorphic scaler. Each channel converts baseband analog video into digital YCbCr 4:2:2 component video, which can then be scaled down to any resolution to 1/256 vertical and 15-bit horizontal in 2-pixel decrements. Composite and S-video inputs are supported. Each channel includes one 9-bit analog-to-digital converter (ADC) with 2× sampling. Sampling is ITU-R BT.601 (27.0) MHz, generated from a single 14.31818-MHz crystal or oscillator input) and is line locked. The output formats can be 8-bit 4:2:2 with discrete syncs or 8-bit ITU-R BT.656 with embedded synchronization. The TVP5154 utilizes Texas Instruments patented technology for locking to weak, noisy, or unstable signals. A real-time control (RTC) output is generated for each channel for synchronizing downstream video encoders. Complementary 4-line adaptive comb filtering is available per channel for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts. A chroma trap filter also is available. An improved fast lock mode can be used when the input video standard is known and the signals on the switching channels are clean. Note, switching from snow and/or noisy channels to good channels takes longer. In fast lock mode, video lock is achieved in three fields or less. Video characteristics, including hue, contrast, brightness, saturation, and sharpness, may be independently programmed for each channel using the industry standard I2C serial interface. The TVP5154 generates synchronization, blanking, lock, and clock signals in addition to digital video outputs for each channel. The TVP5154 includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data processor slices, parses, and performs error checking on teletext, closed caption, and other data in several formats. I2C commands can be sent to one or more decoder cores simultaneously, reducing the amount of I2C activity necessary to configure each core. A register controls which decoder core receives I2C commands, and can be configured such that all four decoders receive commands at the same time. The main blocks for each of the channels of the TVP5154 decoder include:
