TDA10021HT
FEATURES
• 4, 16, 32, 64, 128 and 256 Quadrature Amplitude
Modulation (QAM) demodulator (DVB-C compatible:
ETS 300-429/ITU-T J83 annex A/C)
• High performance for 256 QAM, especially for direct
IF applications
• On-chip 10-bit Analog-to-Digital Converter (ADC)
GENERAL DESCRIPTION
• On-chip Phase-Locked Loop (PLL) for crystal frequency
multiplication (typically 4 MHz crystal)
The TDA10021HT is a single-chip DVB-C channel
receiver for 4, 16, 32, 64, 128 and 256 QAM modulated
signals. The device interfaces directly to the IF signal,
which is sampled by a 10-bit ADC.
• Digital downconversion
• Programmable half Nyquist filter (roll off = 0.15 or 0.13)
• Two Pulse Width Modulated (PWM) AGC outputs with
programmable take over point (for tuner and
downconverter control)
The TDA10021HT performs the clock and the carrier
recovery functions. The digital loop filters for both clock
and carrier recovery are programmable in order to
optimize their characteristics according to the current
application.
• Clock timing recovery, with programmable 2nd-order
loop filter
• Variable symbol rate capability from SACLK/64 to
SACLK/4 (SACLK = 36 MHz maximum)
After baseband conversion, equalization filters are used
for echo cancellation in cable applications. These filters
are configured as either a T-spaced transversal equalizer
or a Decision Feedback Equalizer (DFE), so that the
system performance can be optimized according to the
network characteristics. A proprietary equalization
algorithm, independent of carrier offset, is achieved in
order to assist carrier recovery. A decision directed
algorithm then takes place, to achieve final equalization
convergence.
• Programmable anti-aliasing filters
• Full digital carrier recovery loop
• Carrier acquisition range up to 18% of symbol rate
• Integrated adaptive equalizer (linear transversal
equalizer or decision feedback equalizer)
• On-chip Forward Error Correction (FEC) decoder
(de-interleaver and RS decoder) and fully DVB-C
compliant
The TDA10021HT implements a FORNEY convolutional
de-interleaver of depth 12 blocks and a Reed-Solomon
decoder which corrects up to 8 erroneous bytes. The
de-interleaver and the RS decoder are automatically
synchronized by the frame synchronization algorithm
which uses the MPEG-2 sync byte. Finally descrambling
according to DVB-C standard, is achieved at the Reed
Solomon output. This device is controlled via an I2C-bus.
• DVB compatible differential decoding and mapping
• Parallel and serial transport stream interface
simultaneously
• I2C-bus interface, for easy control
• CMOS 0.2 µm technology.
Designed in 0.2 µm CMOS technology and housed in a
64 pin TQFP package, the TDA10021HT operates over
the commercial temperature range.
APPLICATIONS
• Cable set-top boxes
• Cable modems
• MMDS (ETS 300-749) set-top boxes.

TYPE(1)
VDDD18
1
S
digital supply voltage for the core (1.8 V typ.)
XIN
2
I
XTAL oscillator input pin: a fundamental XTAL oscillator is connected between the
XIN and XOUT pins. The XTAL frequency must be chosen so that the system
frequency SYSCLK (XIN × multiplying factor of the PLL) equals 1.6 times the tuner
output intermediate frequency; i.e. SYSCLK = 1.6 × IF.
XOUT
3
O
XTAL oscillator output pin: a fundamental XTAL oscillator is connected between the
XIN and XOUT pins
VSSD18
4
G
digital ground for the core
SACLK
5
O
sampling clock: this output clock can be fed to an external 10-bit ADC as the
sampling clock; SACLK = SYSCLK/2
TEST
6
I
test input pin: in normal mode, pin TEST must be connected to ground
VDDD18
7
S
digital supply voltage for the core (1.8 V typ.)
VSSD18
8
G
digital ground for the core
AGCTUN
9
O/OD
first PWM encoded output signal for AGC tuner: this signal is fed to the AGC
amplifier through a single RC network. The maximum signal frequency on the
VAGC output is XIN/16. AGC information is refreshed every 1024 symbols.
IICDIV
10
I
IICDIV: this pin allows the frequency of the I2C-bus internal system clock to be
selected, depending on the crystal frequency. The internal I2C-bus clock is a
division of XIN by 4IICDIV.
AGCIF
11
O/OD
SADDR
12
I
SADDR is the LSB of the I2C-bus address of the TDA10021HT. The MSBs are
internally set to 000110. Therefore the complete I2C-bus address of the
TDA10021HT is (MSB to LSB) 0, 0, 0, 1, 1, 0 and SADDR.
VDDD50
13
S
digital supply voltage for the pad 5.0 V (necessary for 5 V tolerant inputs)
VDDD33
14
S
digital supply voltage for the pads (3.3 V typ.)
VSSD33
15
G
digital ground for the pads
CLR#
16
I
the CLR# input is asynchronous and active LOW, and clears the TDA10021HT:
When CLR# goes LOW, the circuit immediately enters its reset mode and normal
operation will resume 4 XIN falling edges after CLR# returns HIGH. The I2C-bus
register contents are all initialized to their default values. The minimum width of
CLR# at LOW level is 4 XIN clock periods.
SCL
17
I
I2C-bus clock input: SCL should nominally be a square wave with a maximum
frequency of 400 kHz. SCL is generated by the system I2C-bus master.
SDA
18
I/OD
SDA is a bidirectional signal: it is the serial input/output of the I2C-bus internal block.
A pull-up resistor (typically 4.7 kΩ) must be connected between SDA and VDDD50 for
proper operation (open-drain output).
SDAT
19
I/OD
SDAT is equivalent to SDA I/O of the TDA10021HT but can be 3-stated by I2C-bus
programming. It is actually the output of a switch controlled by parameter BYPIIC of
register TEST (index 0F). SDAT is an open-drain output and therefore requires an
external pull-up resistor.

DESCRIPTION
second PWM encoded output signal for the AGC IF: This signal is fed to the AGC
amplifier through a single RC network. The maximum signal frequency on the
VAGC output is XIN/16. AGC information is refreshed every 1024 symbols.
However AGCIF can also be configured to output a PWM signal, the value of which
can be programmed through the I2C-bus interface.

SCLT
20
OD
SCLT can be configured to be a control line output or to output the SCL input. This
is controlled by parameter BYPIIC and CTRL_SCLT of register TEST (index 0F).
SCLT is an open-drain output and therefore requires an external pull-up resistor.

when HIGH this pin enables the serial output transport stream through the
boundary scan pins TRST, TDO, TCK, TDI and TMS (serial interface). Must be set
LOW in bist and boundary scan mode.
TCK
22
I/O
test clock: an independent clock used to drive the TAP controller in boundary scan
mode. In normal mode of operation, TCK must be set LOW. In serial stream mode,
TCK is the clock output (OCLK).
TDI
23
I/O
test data input: the serial input for test data and instruction in boundary scan mode.
In normal mode of operation, TDI must be set LOW. In serial stream mode, the TDI
is the PSYNC output.

S
digital supply voltage for the core (1.8 V typ.)
VSSDI8
25
G
digital ground for the core
TRST
26
I/O
test reset: this active LOW input signal is used to reset the TAP controller in
boundary scan mode. In normal mode of operation, TRST must be set LOW. In
serial stream mode, TRST is the uncorrectable output (UNCOR).
TMS
27
I/O
test mode select: this input signal provides the logic levels needed to change the
TAP controller from state to state. In normal mode of operation, TMS must be set to
HIGH. In serial stream mode, TMS is the DEN output.
TDO
28
O
test data output: this is the serial test output pin used in boundary scan mode.
Serial data is provided on the falling edge of TCK. In serial stream mode, TDO is
the data output (DO).
GPIO
29
OD
GPIO can be configured by the I2C-bus either as:
• A Front-End Lock indicator (FEL) (default mode)
• An active LOW output interrupt line (IT) which can be configured by the I2C-bus
interface
• A control output pin programmable by I2C-bus.
GPIO is an open-drain output and therefore requires an external pull-up resistor.

G
digital ground for the pads
CTRL
32
OD
CTRL is a control output pin programmable by the I2C-bus. CTRL is an open-drain
output and therefore requires an external pull-up resistor.
UNCOR
33
O
uncorrectable packet: this output signal is HIGH when the provided packet is
uncorrectable (during the 188 bytes of the packet). The uncorrectable packet is not
affected by the Reed Solomon decoder, but the MSB of the byte following the sync
byte is forced to logic 1 for the MPEG-2 process: error flag indicator (if RSI and IEI
are set LOW in the I2C-bus table).
PSYNC
34
O
pulse synchro: this output signal goes HIGH when the sync byte (0x47) is provided,
then it goes LOW until the next sync byte
OCLK
35
O
output clock: this is the output clock for the DO[7:0] data outputs. OCLK is internally
generated depending on which interface is selected.
DEN

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
SOLDERING
Introduction to soldering surface mount packages
This text gives a very brief insight to a 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).
• 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;
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering can still be used for
certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.
– 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.
• For packages with leads on four sides, the footprint must
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.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
During placement and before 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.
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 dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
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.
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.
Wave soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
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:

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 to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
