Multi-channel filter DAC UDA1328T

8 FUNCTIONAL DESCRIPTION

8.1 System clock

The UDA1328 operates in slave mode only, this means
that in allapplications the system must provide the system
clock.The system frequency is selectable.Theoptionsare
256fs, 384fs, 512fsand 768fsfor the L3 modeand 256fsor
384fs for the static mode. The system clock must be
frequency-locked to the digital interface signals.

It should be noted that the UDA1328 can operate from
5 to 100 kHz sampling frequency (fs). However in 768f

s

mode the sampling frequency must be limited to 55 kHz.

8.2 Application modes

Operating mode can be set with the STATIC pin, either to
L3 mode (STATIC = LOW) or to the static mode
(STATIC = HIGH). See Table 1 for pin functions in the
static mode.

Notes

1. SF1 and SF0 are the Serial Format inputs (2-bit).

2. X means that the pin has no function in this mode and
can best be connected to ground.

8.3 Interpolation filter (DAC)

8.4 Digital silence detection

The UDA1328 can detect digital silence conditions in
channels 1 to 6, and report this via the output pin DS. This
function is implemented to allow for external manipulation
of the audio signal in the absence of program material,
such as muting or recorder control.

An active LOW output is produced at the DS pin if the
channels selected via L3 or for allchannels in staticmode,
carries all zeroes for at least 9600 consecutive audio
samples (equals 200 ms for fs= 48 kHz). The DS pin is
also active LOW when the output is digitally muted either
via the L3 interface or via the STATIC pin.

In static mode all channels participate in thedigital silence
detection. In L3 mode control each channel can be set,
either to participate in the digital silence detection or not.

8.5 Noise shaper

The 3rd-order noise shaper operates at 128fs. It shifts
in-band quantization noise to frequencies well above the
audio band. This noise shaping technique enables high
signal-to-noise ratios to be achieved. The noise shaper
output is converted into an analog signal using a Filter
Stream DAC (FSDAC).

8.6 Filter stream DAC

The FSDAC is a semi-digital reconstruction filter that
converts the 1-bit data stream of the noise shaper to an
analog output voltage. The filter coefficients are
implemented as current sources and are summed at
virtual ground of the output operational amplifier. In this
way very high signal-to-noise performance and low clock
jitter sensitivity is achieved. No post-filter is neededdue to
the inherent filterfunction of the DAC. On-board amplifiers
convert the FSDAC output current to an output voltage
signal capable of driving a line output.

The digital filter interpolates from 1 to 128fs by cascading
a half-band filter and a FIR filter, see Table 2. The overall
filter characteristic ofthe digital filters is illustrated in Fig.3,
andthe pass-band ripple isillustratedin Fig.4. Both figures
are with a 44.1 kHz sampling frequency.

The output voltage of the FSDAC scales proportionally
with the power supply voltage.

8.7 Static mode

The UDA1328 is set to static mode by setting the STATIC
pin HIGH. The function of 6 pins of the device now get
another function as can be seen in Table 1.

8.7.1 SYSTEM CLOCK SETTING
In static mode pin 18 (L3CLOCK) is used to select the

system clock setting.When pin 18 is LOW, the device isin
256fs mode, when pin 18 is HIGH the device is in 384f

s

mode.

44.1 kHz de-emphasis 1 0
48 kHz de-emphasis 1 1

8.7.3 DIGITAL INTERFACE FORMATS

Instaticpin mode the digitalaudiointerfaceformats can be
selected via pin 17 (SF1) and 19 (SF0). The following
interface formats can be selected (see also Table 4):

• I2S-bus with data word length of up to 24 bits

• LSB-justified format with data word length of

16, 20 or 24 bits.

8.8 L3 mode

The device is set to L3 mode by setting the STATIC pin to
LOW. The device can then be controlled via the L3
microcontroller interface (see Chapter 9).

8.8.1 DIGITAL INTERFACE FORMATS
The following interface formats can be selected in the

L3 mode:

• I2S-bus with data word length of up to 24 bits

• MSB-justified with data word length of up to 24 bits

• LSB-justified format with data word length of 16, 18,

20 or 24 bits.

8.8.2 L3 ADDRESS
TheUDA1328canbe addressed via the L3 microcontroller

interface using oneof two addresses.This is done in order
to individually control the UDA1328 and other Philips
DACs or CODECs via the same L3 bus.

The address can be selected using pin 25 (DEEM0) in
L3 mode.When pin 25 isset LOW, theaddress is 000100.
When pin 25 is set HIGH the address is 000101.

It should be noted that thedigital audio interfaceholds that
the BCK frequency can be 64 times the WS maximum

Multi-channel filter DAC UDA1328T

9 L3 INTERFACE DESCRIPTION

The following system and digital sound processing
features can be controlled in the microcontroller mode of
the UDA1328:

• Data input format

• De-emphasis for 32, 44.1, 48 and 96 kHz

• Volume control: master and for individual channels

• Soft or quick mute: master and for individual channels

• Output polarity control: master and for individual

channels

• Digital silence control: master and for individual
channels

• Power-down mode.

Theexchange of dataand control information betweenthe
microcontroller and the UDA1328 is accomplished via a
serial hardware interface comprising the following pins:

L3DATA: microcontroller interface data line
L3MODE: microcontroller interface mode line
L3CLOCK: microcontroller interface clock line.

Information transfer via the microcontroller bus is
organized LSB firstand is in accordance with the socalled
‘L3’ format, in which two different modes of operation can
be distinguished. The address mode and data transfer
mode are illustrated in Figs 6 and 7.

The address mode is required to select a device
communicating via the L3-bus and to define the
destination registers for the data transfer mode. Data
transfer for the UDA1328 can only be in one direction;
inputto the UDA1328 toprogramits sound processing and
other functional features.

9.1 Address mode

The address mode is used to select a device for
subsequent data transfer and to define the destination
registers. The address mode is characterizedby L3MODE
being LOW and a burst of 8 pulses on L3CLOCK,
accompanied by 8 data bits. The fundamental timing is
shown in Fig.6. Data bits 0 and 1 indicate the type of
subsequent data transfer as given in Table 5.

Table 5 Selection of data transfer

BIT 1 BIT 0 TRANSFER

0 0 data (volume, de-emphasis, mute,

digital silence mode, polarity control)
0 1 not used
1 0 status (system clock frequency,

data input format, mute mode,

power control)
1 1 not used

Data bits 7 to 2 represent a 6-bit deviceaddress, with bit 7
being the MSB and bit 2 the LSB. The address of the
UDA1328 is 000100 (bit 7 to bit 2) when L3ADR
(DEEM0) = LOW or 000101 when L3ADR = HIGH. In the
eventthat the UDA1328receivesa different address, itwill
deselect its microcontroller interface logic.

9.2 Data transfer mode

The selection preformed in the address mode remains
active during subsequent data transfers, until the
UDA1328 receives a new address command. The
fundamental timing of data transfers is essentially the
same as in the address mode, shown in Fig.6. The
maximuminputclockand data rate is 64fs.All transfersare
byte wise, i.e. they are based on groups of 8 bits. Data will
be stored in the UDA1328 after the eighth bit of a byte has
been received. A multibyte transfer is illustrated in Fig.8.

9.2.1 PROGRAMMING THE SOUND PROCESSING AND

OTHER FEATURES

The sound processing and other feature values are stored
inindependent registers. The first selectionoftheregisters
is achieved by the choice of data type that is transferred.
This is performed in the address mode, bit 1 and bit 0
(see Table 5). The second selection is performed by the
2 MSBs of the data byte (bit 7 and bit 6). The other bits in
thedata byte (bit 5 to bit 0) isthe value that isplaced in the
selected registers.

When the data transfer of type ‘data’ is selected, the
features volume, sub volume, de-emphasis, mute, digital
silence settings, output polarity control and channel
selection can be controlled. When thedata transfer oftype
‘status’ is selected, the features system clock frequency,
data input format, mute mode and power control can be
controlled.

9.3 Feature settings

In the UDA1328 there are features that can be controlled
either per-channel or all at the same time. These features
are:

• Volume control

• Sub volume control

• Mute

• Output polarity control

• Digital silence detect.

Whena ‘per-channel’ setting is requiredforthese features,
the ACH bit (see Table 7) must be set to logic 0 before
writing a new value to one of the features. Once this has
been performed a channel is selected via the CH2 to CH0
bits.Thefeaturesforthis channel can be controlled without
sending the same channel address again (low
microcontroller mode).

When the ACH bit is set to logic 1, which means ‘all
channels select’, all channels will be set to thesame value
of the feature sent afterwards.

For the digital silence detector it holds that the DS pin is
either active on the selected channel when bit ACH is set
to logic 0 before writing the DSM bit, or the DS pin is active
on all channels when the ACH bit is set to logic 1.

19 SOLDERING

19.1 Introduction to soldering surface mount
packages

Thistextgives a very briefinsighttoa complex technology.
A more in-depth account of soldering ICs can be found in
our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for
certainsurfacemount ICs, but it isnotsuitablefor fine pitch
SMDs. In these situations reflow soldering is
recommended.

19.2 Reflow soldering

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
tothe printed-circuit board byscreen printing, stencilling or
pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.

Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.

19.3 Wave soldering

Conventional single wave soldering is not recommended
forsurfacemount devices (SMDs) or printed-circuitboards
with a high component density, as solder bridging and
non-wetting can present major problems.

To overcome these problems the double-wave soldering
method was specifically developed.

If wave soldering is used the following conditions must be
observed for optimal results:

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the
printed-circuit board.

The footprint must incorporate solder thieves at the
downstream end.

• Forpackageswith leads on four sides,thefootprintmust
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.

During placement andbefore soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

19.4 Manual soldering

Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.

When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

Notes

1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the

“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”

.

2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).

3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.

4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e)equal toor larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
