Princeton Technology Corp PT2399
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 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

APPLICATION CIRCUIT
ECHO
PT2399
Note:
External Resistor having a value of 10 Kto 50 Kmay be used. The recommended Resistor Value(R) is 10 K. When the value of the Resistor (R)
increases, the range of the Delay Time also increases.
