TVP5154APNP

Product Summary

The TVP5154APNP 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 TVP5154APNP 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 TVP5154APNP are independently controllable. The decoders share one crystal for all channels and for all supported standards. The TVP5154APNP 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 TVP5154APNP decoder allows for low power consumption. The decoder consumes less than 720 mW of power in typical operation. The applications of the TVP5154APNP include security camera systems, large format video wall displays, games systems.
