The TDA8295 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 is 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 TDA8275A or 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.
Note:The recommended ADC programming deviates from default setting and needs to be set explicitly by I2C-bus protocol after hardware reset
