Philips Semiconductors
Preliminary specification
IEC 958 audio DAC
UDA1350AH
1
FEATURES
1.1
General
2.7 to 3.6 V power supply
Integrated digital filter and Digital-to-Analog Converter
(DAC)
Master-mode data output interface for off-chip sound
processing
256f
s
system clock output
20-bit data-path in interpolator
High performance
No analog post filtering required for DAC.
1.2
Control
Controlled either by means of static pins or via the
L3 microcontroller interface.
1.3
IEC 958 input
On-chip amplifier for converting IEC 958 input to CMOS
levels
Selectable IEC 958 input channel, one out of two
Lock indication signal available on pin LOCK
Lock indication signal combined on-chip with the Pulse
Code Modulation (PCM) status bit; in case non-PCM
has been detected pin LOCK indicates out-of-lock
Key channel-status bits available via L3 interface (lock,
pre-emphasis, audio sample frequency, two channel
PCM indication and clock accuracy).
1.4
Digital output and input interfaces
When the UDA1350AH is clock master of the data
output interface:
– BCKO and WSO signals are output
– I
2
S-bus or LSB-justified 16, 20 and 24 bits formats
are supported.
When the UDA1350AH is clock slave of the data input
interface:
– BCK and WS signals are input
– I
2
S-bus or LSB-justified 16, 20 and 24 bits formats
are supported.
1.5
Digital sound processing and DAC
Pre-emphasis information of IEC 958 input bitstream
available in L3 interface register and on pins
Automatic de-emphasis when using IEC 958 input with
32.0, 44.1 and 48.0 kHz audio sample frequencies
Soft mute by means of a cosine roll-off circuit selectable
via pin MUTE or the L3 interface
Interpolating filter (f
s
to 128f
s
) by means of a cascade of
a recursive filter and a FIR filter
Third-order noise shaper operating at 128f
s
generates
bitstream for the DAC
Filter stream digital-to-analog converter.

APPLICATIONS
Digital audio systems.

GENERAL DESCRIPTION
Available in two versions:
UDA1350AH:
– Full featured version in QFP44 package.
UDA1350ATS:
– Only IEC 958 input to DAC in SSOP28 package.
The UDA1350AH is a single chip IEC 958 audio decoder
with an integrated stereo digital-to-analog converter
employing bitstream conversion techniques.
