Description

The PT2399 is a single chip echo processor IC utilizing CMOS technology. Which accept analog audio input signal, a high sample rate ADC transfer the analog signal into a bit stream then storage to internal 44Kbit RAM, after processing the bit stream will de-modulate by DAC and lowpass filter. Overall delay time is determined by internal VCO clock frequency, and user can easy to change the VCO frequency by changing the external resistance. The PT2399 performs low distortion (THD<0.5%@0.5Vrms) and low noise (No<-90dBV) characteristic for audio purpose, and pin arrangement and application circuit are optimized foreasy PCB layout and cost saving advantage. PT2399 Features &bull; CMOS technology&bull; Least external components&bull; Auto reset Function prevent POP noise&bull; Low noise, SNR better than 90dB (typical)&bull; Low distortion, THD= 0.5%(typical)&bull; User adjustable VCO clock frequency PT2399 Applications &bull; Video Tape Recorder&bull; Video Compact Disk&bull; Television&bull; CD Player&bull; Car Stereo&bull; KARAOKE Mixer&bull; Electronic Musical Instrument&bull;Audio Equipment with Echo Processor
