TDA8296 Datasheet | NXP Semiconductors

description 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 remended content. However, if this is not suitable, free programming is always possible. Note: Register 06h has to be reprogrammed to new value C4h (see Section 9.2 and Section 9.3.1). 2. Features and benefits - Digital IF demodulation for all analog TV standards worldwide (M/N, B/G/H, D/K, I, L and L-accent standard) - Multistandard true synchronous demodulation with active carrier regeneration - Alignment-free - 16 MHz typical reference frequency input (from low IF tuner) or operating as crystal oscillator - Internal PLL synthesizer which allows the use of a low-cost crystal (typically 16 MHz) - Especially suited for the NXP Silicon Tuner TDA1827x - No SAW filter needed - Low application effort and external ponent count in bination with the TDA1827x - Simple upgrade of TDA8295 possible - 12-bit low power IF ADC on chip running with 54 MHz or 27 MHz - Two 10-bit DACs on chip for CVBS and SSIF or audio - Easy programming for I2C-bus - High flexibility due to various I2C-bus programming registers - I2C-bus interface and I2C-bus feed-through for tuner programming - Four I2C-bus addresses selectable via two external pins ..net NXP Semiconductors Digital global standard low IF demodulator for analog TV and FM radio ..net - Gated IF AGC acting on black...
