SC5399
ECHO SOUND EFFECT PROCESSOR
DESCRIPTION
SC5399 is an echo audio processor IC utilizing CMOS technology
which is equipped with ADC and DAC, high sampling frequency and
internal memory of 44K digital processing is used to generate the delay
time. It also features an internal VCO circuit in the system clock,
thereby, making the frequency easily adjustable. SC5399 boast of very
low distortion (THD<0.5%) and very low noise (N0<-90dBV), thus
producing high quality audio output. The pin assignments and
application circuit are optimized for easy PCB layout cost saving
advantage.
