PT2399 Datasheet | Princeton Technology Corp

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 low pass 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<-90d BV) characteristic for audio purpose, and pin arrangement and application circuit are optimized for easy PCB layout and cost saving advantage. APPLICATIONS - KARAOKE Mixer - CD/DVD Player/Recorder - Multimedia TV - Car Entertainment System - Music Instrument effecter - Electronics Toy BLOCK DIAGRAM PT2399 Echo Processor IC FEATURES - CMOS technology - Least external ponents - Auto reset Function prevent POP noise - Low noise, SNR better than 90d B (typical) - Low distortion, THD= 0.5%(typical) - User adjustable VCO clock frequency.

The remended Resistor Value(R) is 10 KΩ. When the value of the Resistor (R) increases, the range of the Delay Time also increases. SURROUND/DELAY Note: Please refer to Table 1 for the Resistor/Delay Time values.
