PS9850
Multi-channel Digital Audio Processor
Eight-channels, 192kHz, 24-bits
Digital Audio Processor for Full Digital Amplifier
Introduc-
tion_______________________
The PS9850 is a highly integrated system-on-chip audio
solution for multi-channel AV systems such as upper 5.1
channels, 6.1 channels or 7.1 channels. This device is a
high performance PWM modulator and a high resolution
digital audio processor.
This device uses AD modulation operating at a 384kHz
switching rate, supports AM interference rejection function,
and has PWM sequences for pop-less.
This device has an asynchronous sample rate converter
for a variety of input sample rates with an embedded jitter
correction function. For high performances and high reso-
lutions, audio processors operate 30bit data paths and a
192kHz sample rate.
This processor consists of equalizers, volume controls, a
bass management and automatic gain limiting functions.
Equalizers are fully programmable that have 69 band bi-
quad filters with either a static or graphic mode and have
usable preset graphic equalizer.
This device is operated with a single power source, as it
has regulators for its core. This device has a built-in PLL
without external loop filter. Therefore the external compo-
nents are minimized.
