Preliminary specification
UDA1335H
The firmware for the microcontroller must be located in an
external (E)PROM.
The ADAC enables the wide and continuous range of input
sampling frequencies. By means of a Sample Frequency
Generator (SFG), the ADAC is able to reconstruct the
average sample frequency from the incoming audio
samples. The ADAC also performs the sound processing.
The ADAC consists of a FIFO, a unique audio feature
processing DSP, the SFG, digital upsampling filters, a
variable hold register, a Noise Shaper (NS) and a Filter
Stream DAC (FSDAC) with integrated filter and line output
drivers. The audio information is applied to the ADAC via
the USB processor or via the digital I/O input.
The ADIF consists of an Programmable Gain Amplifier
(PGA), an Analog-to-Digital Converter (ADC) and a
Decimator Filter (DF). An Analog Phase Lock Loop (APLL)
or oscillator is used for clocking the ADIF. The clock
frequency for the ADIF can be controlled via the
microcontroller. Several clock frequencies are possible for
sampling the analog input signal at different sampling
rates.
Via the digital I/O-bus, an external DSP can be used for
adding extra sound processing features for the audio
received from the PC.
The UDA1335H supports the digital I/O and the I2S-bus
interface, with standard I2S-bus data input format and the
LSB justified serial data input format with word lengths of
16, 18 and 20 bits.
The wide dynamic range of the bitstream conversion
technique used in the UDA1335H guarantees a high audio
sound quality.
APPLICATIONS
USB monitors
USB speakers
USB headsets
USB telephone/answering machines
USB links in consumer audio devices.
