1.2 Description
The TVP5151 device is an ultralow-power NTSC/PAL/SECAM video decoder. Available in a space-saving
48-terminal PBGA package or a 32-terminal TQFP package, the TVP5151 decoder converts NTSC, PAL,
and SECAM video signals to 8-bit ITU-R BT.656 format. Discrete syncs are also available. The optimized
architecture of the TVP5151 decoder allows for ultralow power consumption. The decoder consumes
138-mW power under typical operating conditions and consumes less than 1 mW in power-down mode,
considerably increasing battery life in portable applications. The decoder uses just one crystal for all
supported standards. The TVP5151 decoder can be programmed using an I
2
C serial interface.
The TVP5151 decoder converts baseband analog video into digital YCbCr 4:2:2 component video.
Composite and S-video inputs are supported. The TVP5151 decoder includes one 9-bit analog-to-digital
converter (ADC) with 2× sampling. Sampling is ITU-R BT.601 (27.0 MHz, generated from the 27.000-MHz
crystal or oscillator input) and is line locked. The output formats can be 8-bit 4:2:2 or 8-bit ITU-R BT.656
with embedded synchronization.
