The PT2399 is a CMOS integrated circuit designed to create echo and delay effects in audio signals. It's a single-chip solution that includes an ADC, DAC, 44Kbit RAM, and a VCO for processing audio signals and generating delay. The PT2399 is commonly used in applications like karaoke mixers, music instrument effectors, and car entertainment systems.
Here's a more detailed explanation:
Echo/Delay Creation:
The PT2399 processes incoming analog audio signals, converts them to digital, stores them in internal memory, and then reproduces them after a delay, creating the echo effect.
Internal Components:
It features an ADC (Analog-to-Digital Converter) to convert the input signal to digital format, a 44Kbit RAM for storing the digitized audio, and a DAC (Digital-to-Analog Converter) to convert the processed digital signal back to analog output.
Delay Time Adjustment:
The internal VCO (Voltage-Controlled Oscillator) controls the delay time, and external resistance allows users to adjust the VCO frequency, thus changing the delay duration.
Versatile Applications:
The PT2399 is used in various audio applications, including karaoke mixers, music instrument effectors, CD/DVD players, and car entertainment systems.
