TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9456F Single Chip Surround LSI with a Built-in SRS TC9456F TC9456F is single Chip surround LSI with a built-in SRS for portable equipment, Mini compo. As built-in ADC/DAC, Surround, Digital equalizer, bass boost and SRS of 3D sound reproduction technology, this IC constructs DSP function. Features • Built-in 3channel AD converter. THD: −65dB S/N: 78dB (typ.) Built-in ope amp for pre-filter. • Built-in 2channel DA converter. Weight: 1.07 g (typ.) THD: −85dB S/N: 93dB (typ.) Built-in 3rd analog filter. • Input: 3 analog channel, 1 digital stereo port. Digital input format: MSB first 16, 18, 20 bit effective data before change point of LRCK or I2S. • Output: 2 analog output/1 digital stereo port. Digital output format: MSB first 16, 20 bit effective data before change point of LRCK or I2S. • Built-in 64 Kbit delay RAM. • DSP function • SRS: Eliminate existing sweet spot and restore spatial information, direction cues and other sonic nuance which are either missing or altered during and playback process. Correspondence only for fs = 44.1 kHz with SRS. • Surround: Real surround to use delay, simulate sound field of hole, church, stadium and etc. • Bass boost: Dynamic surround to respond an input • 3 Band parametric equalizer: Equalizer of a high precision of 18 bit coefficient • Package is QFP 44 pins.
