NXP TDA8296模拟电视和FM收音机通用数字低IF解调方案

NXP 公司的TDA8296是模拟电视和FM收音机通用数字低IF信号PLL解调器，适合所有的模拟TV标准，包括M/N, B/G/H, D/K, I, L 和 L音标准。器件通过两个DAC还提供CVBS和 SSIF/单频音频。TDA8296特别适合和NXP的硅调谐器TDA1827x.配合使用。所有的处理都在数字域完成，主要应用在TV，录音机和PC TV。本文介绍了TDA8296主要特性和优势，功能方框图，典型应用电路图以及多种IF输入电路。

TDA8296：Digital global standard low IF demodulator for analog TV and FM radio

The TDA8296 is an alignment-free digital multistandard vision and sound low IF signal PLL demodulator for positive and negative video modulation including AM and FM mono sound processing. It can be used in all countries worldwide for M/N, B/G/H, I, D/K, L and L-accent standard. CVBS and SSIF/mono audio are provided via two DACs. FM radio preprocessing is included for simple interfacing with demodulator/stereo decoder backends.

The IC is especially suited for the application with the NXP Silicon Tuner TDA1827x. All the processing is done in the digital domain.

The chip has an ‘easy programming’ mode to make the I2C-bus protocol very simple. In principle, only one bit sets the proper standard with recommended content. However, if this is not suitable, free programming is always possible.
