The receive path implements a direct down-conversion
architecture that eliminates the need for Intermediate
Frequency (IF) components. The CX74063-3x receiver consists
of three integrated Low Noise Amplifiers (LNAs), a quadrature
demodulator, tunable receiver baseband filters, and a DCoffset correction sequencer.
In the transmit path, the device consists of an In-phase and
Quadrature (I/Q) modulator within a frequency translation loop
designed to perform frequency up-conversion with high output
spectral purity. This loop also contains a phase-frequency
detector, charge pump, mixer, programmable dividers, and
high power transmit Voltage Controlled Oscillators (VCOs) with
no external tank required. With the integrated gain controller
(and an integrator ), the device realizes the Power Amplifier
Control (PAC) functionality when combined with a coupler, a
Radio Frequency (RF) detector and a Power Amplifier (PA).
The CX74063-3x also features an integrated, fully
programmable, sigma-delta fractional-N synthesizer suitable
for GPRS multi-slot operation. Except for the loop filter, the
frequency synthesizer function, including a wideband VCO, is
completely on-chip. The reference frequency for the
synthesizer is supplied by the integrated crystal oscillator
circuitry.
The 56-pin 8x8 RF Land Grid Array (RFLGA™) device package
and pin configuration are shown in Figure 1. A functional block
diagram is shown in Figure 2. Signal pin assignments,
functional pin descriptions, and equivalent circuitry are
provided in Table 1.

A 3-wire serial interface controls the transceiver and
synthesizer. The receiver gain control, as well as the division
ratios and charge pump currents in the synthesizer and
transmitter, can be programmed using 24-bit words. These
24-bit words are programmed using the 3-wire input signals
CLK, DATA, and LE. To ensure that the data stays latched in
power down mode, pin 43 (VDDBB) must be continuously
supplied with voltage. This pin is provided for the digital
sections to allow power supply operation compatible with
modern digital baseband devices.
The TXENA, RXENA, and SXENA signals separately enable the
CX74063-3x transmitter, receiver, and synthesizer sections.
TXENA and RXENA should be held low during programming.
SXENA should be held high during the programming of the R3
IP2 Calibration Register. (These timing signals are detailed in
Figures 9, 10, and 11.)

Receive Section
LNA and Quadrature Demodulator
Three separate LNAs are integrated to address different bands
of operation. These LNAs have separate single-ended inputs,
which are externally matched to 50 Ω. The gain is switchable
between high (i.e., 15 dB typical) and low (i.e., –5 dB GSM,
–7 dB DCS, and –5 dB PCS typical) settings. The LNA outputs
feed into a quadrature demodulator that downconverts the RF
signals directly to baseband. Two external 470 pF capacitors
are required at the demodulator output to suppress the out-ofband blockers.
Baseband Section
An off-chip capacitor and three fixed poles of on-chip, low
pass filtering provide rejection of strong in- and out-of-band
interferers. In addition, a tunable, four-pole gmC filter provides
rejection of the adjacent channel blockers. Incorporated within
the fixed-pole filters are two switchable gain stages of 18 dB
and 12 dB gain steps, respectively. There is an additional
programmable gain amplifier with a gain range from 0 to + 34
dB, selectable in 2 dB steps in the four-pole tunable filter. The
final filter output feeds an amplifier with a gain range from 0 to
30 dB, selectable in 6 dB steps.
There is an additional gain stage on the four-pole tunable filter
output, the auxiliary gain stage, selectable at 0 dB or + 6 dB.
The gain control ranges are shown in Figure 3.
Recommended combinations of individual block gain settings
are shown in Table 22 for GSM900, Table 23 for DCS1800, and
Table 24 for PCS1900.
For added baseband interface flexibility, the four-pole filter, its
associated Variable Gain Amplifier (VGA), and DC offset
correction loop can be bypassed and turned off for current
savings.
In Table 2 the typical locations of all eight receiver baseband
poles are given. The final four poles are produced by the
tunable gmC filter, as set by the external resistor
(recommended value is 39.2 kΩ, 1%) placed from pin 29 to
ground.
DC Offset Correction
Three DC offset correction (DCOC) loops ensure that DC
offsets, generated in the CX74063-3x, do not overload the
baseband chain at any point. After compensation, the
correction voltages are held on capacitors for the duration of
the receive slot(s). Internally, on-chip timing is provided to
generate the track and hold (T_H) signals for the three
correction loops.
The timing diagram for the DC offset correction sequence with
reference to the receive slot is shown in Figure 4. A rising edge
on either the RXENA signal, selected via the serial interface,
places the DC compensation circuitry in the track mode.
The timing parameters for each of the three compensation
loops, tt_H1, tt_H2, and tt_H3, and the time between compensation
start and the LNA being turned on, tFEENA, are defined via an
internal state machine. The state machine is preprogrammed
with fixed default values, but may be readjusted via the serial
interface.
The timing parameters for the three compensation loops and
the LNA power-up are each independently defined, relative to
the compensation start. Therefore, they may be programmed
to occur in any order, but the sequences shown in Figure 4 and
Figure 5 are recommended. The device default timing is shown
in Figure 5, with a total time of 60 μs. Individual default timings
are given in Table 17. For user-programmed timing, the total
time may be set as short as approximately 10 μs when FREF
has a 13 MHz clock applied. However, the shortest
recommended total time is approximately 30 μs, since at the
highest gain settings, the resulting DC may degrade as
correction time is reduced.
AM Suppression and IP2 Calibration
For direct conversion GSM applications, it is imperative to have
extremely low second-order distortion. Mathematically,
second-order distortion of a constant tone generates a DCterm proportional to the square of the amplitude. A strong
interfering amplitude-modulated (AM) signal is therefore
demodulated by second-order distortion in the receiver front
end, and generates an interfering baseband signal.
For these tunable poles, Table 2 gives the pole location as a
function of this resistor.

Figure 5. DC Offset Correction Timing (LNA On During Part of the DC Offset Correction Sequence)
A commonly used measure for receiver second-order distortion
is the second-order intercept point, IP2. For example, to ensure
that the unwanted baseband signals are 9 dB below the
wanted signal required under the AM suppression test for type
approval (see 3GPP TS 51.010-1), an input IP2 of 43 dBm is
required:
The CX74063-3x receiver includes a circuit that minimizes
second-order distortion. This IP2 calibration circuit effectively
compensates any second-order distortion in the receive chain
that would otherwise generate unwanted baseband signals in
the presence of strong interfering signals. When calibrated
correctly, the CX74063-3x IP2 meets the GSM AM suppression
test requirements in all bands with good margin.
To calibrate IP2, apply a strong RF signal at the receiver input
and observe the resulting DC voltage level change at the
receiver I/Q outputs. The exact frequency and level of the
signal applied for the purpose of the calibration are not critical.
The signal should, however, be within the receive band, but at
least 6 MHz offset from the frequency to which the receiver is
tuned. The level should be high enough to cause a notable DC
shift at the I/Q outputs. A recommended value is –30 dBm at
the LNA input, which applies to all three LNAs.
A set of I/Q compensation coefficients can then be
programmed to the device to minimize the DC voltage shift
resulting from the second-order distortion. When the DC due to
the interfering signal is minimized, the IP2 performance is
optimized.
Note:
SXENA, pin 38, must be held high, and a clock signal
must be present on XTAL, pin 34, during the
programming of the IP2 calibration coefficients in
Register 3, see Table 18.
The IP2 calibration is a one-time factory calibration that should
be done for each band and each individual device for optimum
performance. The determined coefficients must be stored in
nonvolatile memory and programmed to the CX74063-3x upon
each power-up as part of device initialization. There are onchip registers that must be programmed through Register 3
with the appropriate IP2 coefficients for the band in use.
As long as a supply voltage is maintained on pin 43, VDDBB,
the IP2 coefficients for ILOWBAND, IHIGHBAND, QLOWBAND, QHIGHBAND,
programmed to the device remain in the registers. After the
supply voltage has been removed from VDDBB, the coefficients
must be re-programmed to the device again.
Receive/Transmit I/Q Baseband Signals. Separate pins are
provided for receive I/Q outputs and transmit I/Q inputs.
However, for basebands that multiplex these signals, the
receive I/Q outputs and transmit I/Q inputs can be tied
together.
Synthesizer Section
The CX74063-3x includes a fully integrated UHF VCO with an
on-chip LC tank.
A single sigma-delta fractional-N synthesizer can phase-lock
the local oscillator used in both transmit and receive paths to a
precision frequency reference input. Fractional-N operation
offers low phase noise and fast settling times, allowing for
multiple slot applications such as GPRS. The CX74063-3x
frequency stepping function with a 3 Hz resolution allows triple
band operation in both transmit and receive bands using a fully
integrated single integrated on-chip UHF VCO. The fine
synthesizer resolution allows direct compensation or
adjustment for reference frequency errors.

Reference buffer and divider
Fast phase frequency detector and charge pump
For the transmitter VCO frequency, refer to the equations

Digital Frequency Centering
The CX74063-3x uses a novel technique whereby the UHF VCO
frequency range is re-centered each time the synthesizer is
programmed. This technique is called Digital Frequency
Centering (DFC). The DFC technique:
The user must provide the following three parameters:
• The reference divider value, from 1 to 15
• The N-divider value, in a manner similar to an integer-N
synthesizer
• A fractional ratio
• Extends the VCO frequency coverage
• Speeds up settling time
• Ensures robust performance since the VCO is always
operated at the center of its tuning range.
The generated frequency is given by the following equation:
f VCO
where: fVCO
N
FN
R
fREF
FN 

 N + 3.5 + 22  f ref
2 

=
R
Each time the synthesizer is programmed, the DFC circuit is
activated, and the VCO is centered to the programmed
frequency in less than 20 µs. After this, normal Phase Locked
Loop (PLL) operation is resumed and the fine settling of the
frequency is finalized. The DFC typically adjusts the VCO center

and presets the tuning voltage to the center of the range before
the PLL takes over. This speeds up frequency settling and
ensures that the PLL control voltage never operates close to
the rails.

low if an external reference oscillator is used. The buffer may
be disabled by programming bit 3 in the SX1 Control Register
(see Table 13) to logic 0.
The DFC is an adaptive circuit that corrects for any VCO center
frequency errors caused by variations of the integrated VCO
circuit, temperature, supply voltage, aging etc. The VCO can be
centered at any frequency in the range from 1.2 GHz to
1.55 GHz. Once centered, the VCO has a minimum analog
tuning range of 30 MHz.
Transmit Section
To minimize the post-PA filtering requirements and any
additional post-PA losses, the transmit path consists of a
vector modulator within a frequency translation loop. The
translation loop consists of the following:
No calibration or data storage is needed for DFC operation. It is
activated by one of two events:
• When the synthesizer is programmed, the rising edge of the
LE signal starts the DFC cycle and,
• When changing the level of the SXENA signal from low to
high, thereby turning on the synthesizer, the rising edge of
the SXENA signal starts the DFC cycle.
•
•
•
•
•
Crystal Oscillator
A crystal oscillator is designed to provide the reference
frequency for the synthesizer. As shown in Figure 7, the
oscillator uses an external crystal to generate an accurate
oscillation frequency. The reference frequency can be changed
through coarse tuning with an integrated capacitor array or fine
tuning with the integrated varactor diode. The coarse tuning is
done by switching in and out (using a digital word programmed
via the serial interface) the capacitor network (CAP_A and
CAP_B) located at the input of the integrated buffer. The fine
tuning is done by providing a tuning voltage to the integrated
varactor diode. Table 20 describes the control bits.

Translational Loop
The translational loop takes baseband analog I/Q signals and
modulates them with the mixed product of transmitter output
and LO signal, as shown in Figure 6. The unmodulated result is
compared with a divided down LO at the PFD and the
difference is used to control the transmit VCO. The on-chip
Low Pass Filter (LPF) following the mixer attenuates the
unwanted sidebands as well as harmonics.
Transmit VCOs
Two on-chip transmit VCOs are designed to meet GSM850,
EGSM900, DCS1800, and PCS1900 requirements. The
transmit VCOs use the same DFC technique as described in the
Synthesizer section to lock the translational loop. The rising
edge on TXENA initializes the transmit DFC.
An output buffer is provided to drive the baseband circuitry
(XTALBUF, pin 30). The VCXO and buffer circuitry are powered
from pin 33 (VCCF). When VCCF is ramped to a voltage greater
than 2.6 V, the output buffer powers on. The oscillator core
powers up when pin 4 (VCXO_EN) is set to logic 1. If pin 4 is
tied permanently to logic 1, the R6 VCXO Control Register is set
to a defined state by a power-on reset. Pin 4 should be held

Figure 8. PA Controller Block Diagram
Power Amplifier Gain Controller
The device contains an error amplifier/integrator to provide
transmit burst control for an external power amplifier (PA). As
shown in Figure 8, when the device is connected to a PA, an
RF detector, and a coupler, a loop is formed that controls the
transmit power in a multi-band wireless application. The error
amplifier amplifies and integrates the voltage difference
between the RF detector output (PDET) and the power control
input (BBVAPC). The output of the integrator is fed to an
internal gain shaper that drives the gain control input (PAVAPC)
of the external RF PA. The device. provides a bandgap voltage
(PDETVCC) which can be used as the supply voltage for the
external peak detector and can source up to 200 µA.
The PA pre-bias is activated after a programmable delay and
time-referenced from the rising edge of TXENA. The time delay
is set using the serial interface. See Table 19 for details.
Digital Interface
The transceiver and synthesizer are controlled by a single
three-wire serial interface. The transmitter, receiver, and
synthesizer are each enabled through external inputs
according to typical timing requirements as shown in Figures
10 and 11.
Band selection for the CX74063-3x is through the three-wire
serial interface. The PCO signal (pin 3) provides a band
selection control output. DC offset calibration and front-end
activation timing can also be controlled by an on-chip signal
sequencer, precluding the need for separate control signals. All
the logic and the three-wire interface inputs are referenced to
the PCO signal (pin 3).

NOVEMBER 25, 2003
The RX/TX Control Register is used to program the transceiver
and to preset other test word states by setting bit 22 as a
logic 1. If any test words are to be altered from their preset
states, bit 22 must be sent to the RX/TX Control Register again
as a logic 0. Typically, this is done only on power-up since the
device has a zero-power standby mode that retains
programmed test memory.
There are eight additional registers used to program various
functions of the CX74063-3x. The SX1 Control Register is used
to program the fractional-N synthesizer and the SX2
Fractional-N Modulo Register is used to program the modulus.
Four auxiliary registers are used to program the transceiver
besides the RX/TX Control Register, and two 24-bit registers
are used to program the synthesizer:

SX2 Fractional-N Modulo Register. This register is used to
program the 24-bit modulo of the fractional-N synthesizer. The
data is a 22-bit binary coded decimal word that allows the PLL
to lock to precise frequencies. Refer to Table 14.
RX/TX Control Register. This register is used to control divide
ratios and charge pump currents in the transmitter, and to
control gain in the receiver along with the band select function.
Refer to Table 15.
R0 Auxiliary Control Register. This register is used to bypass
the DC offset correction loops and the baseband filters. It also
enables and disables the two on-chip transmit VCOs and
defines the directionality of the LO port, which allows an
external VCO or LO reference to be used or enables the internal
VCO to be monitored. Refer to Table 16.
R2 DC Offset Timing Register. This register sets the timing of
the tracking of the three DC offset cancellation loops and the
time at which the front end turns on relative to the RXENA
signal (pin 1). It allows the front-end to be enabled using the
internal timer. Refer to Table 17.
R3 IP2 Calibration Register. This register is used to perform
2nd order Intercept Point (IP2) calibration by manually adjusting
calibration coefficients. A total of four words need to be set:
IP2 coefficients for I-high band, I-low band, Q-high band, and
Q-low band. Refer to Table 18.
The IP2 coefficient is eight bits long (including polarity) and is
intended to be a factory calibration. An algorithm using a test
tone needs to be used to determine the coefficient for each
individual part.
R4 PAC Timing Control Register. This register is used to set
timing for the PAC pedestal. Refer to Table 19.
R6 and R7 VCXO Control Registers. These registers are used
to control the tuning range and oscillation frequency of the
VCXO. See Tables 20 and 21, respectively.

Package and Handling Information
Because this device package is sensitive to moisture
absorption, it is baked and vacuum packed before shipment
according to IPC J-STD 033 guidelines. Instructions on the
shipping container label regarding exposure to moisture after
the container seal is broken must be followed. These
instructions adhere to IPC J-STD 020A guidelines for handling
moisture sensitive devices. If these instructions are not
followed, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The CX74063-3x transceiver is available in both low
temperature and high temperature attachment packages. The
RFLGA package for the low temperature attachment option
provides a circular-shaped ground pad (CX74063-34). The
RFLGA package for the high temperature options is available
with both a circular-shaped ground pad and a four-quadrant,
split center ground pad (CX74063-35 and CX74063-36,
respectively). Refer to Figures 28 and 29 for package
dimensions.
Guidelines for CX74063-3x low and high temperature
attachment techniques are provided below. For additional
details on attachment techniques, precautions, and
recommended handling procedures, refer to the Skyworks’
Application Note, PCB Design & SMT Assembly Guidelines for
RFLGA Packages, document number 103147.
For The –34 Low Temperature Package Option: If the
CX74063-34 is attached in a reflow oven, the temperature
ramp rate should not exceed 3 °C per second. Maximum
temperature should not exceed 240 °C and the time spent at a
temperature that exceeds 235 °C should be limited to less than
10 seconds.
If the part is manually attached, precaution should be taken to
ensure that the part is not subjected beyond a maximum
temperature of 240 °C or exceeds 235 °C for more than
10 seconds. Care must be taken when this product is attached,
whether it is done manually or in a production solder reflow
environment, to NOT heat the part beyond the recommended
temperature. Measure the temperature on the package itself
by attaching thermocouples to the package body.
For The –35 and –36 High Temperature Package Options: If
the CX74063-35 or the CX74063-36 are attached in a reflow
oven, the temperature ramp rate should not exceed 3 °C per
second. Maximum temperature should not exceed 260 °C and
the time spent at a temperature that exceeds 255 °C should be
limited to less than 15 seconds.

Note 1:
The Pin 1 ID is a triangle or circle.
Note 2:
Brand line 1. The Part Number format is CXPPPPP-DD. The CX prefix is the company identifier. P = five-digit part number,
D = dash number (for example, -34, -35). The CX prefix may not appear on small devices. The Part Number may be
followed by a "P" to indicate a prototype device. (Note 3)
Brand line 2. Lot Number and Lot Split Identifier. The Lot Number format = 6 alphanumeric characters followed by a 1- or
2-digit Lot Split Identifier separated by a decimal point. The format is A12345.2 or A12345.21. (Note 3)
Brand line 3. Date Code and Country of Origin. The Date Code should be the same for the entire Lot Number and Lot Split
Identifier. The first two digits of the Date Code are the current accounting calendar year. The last two digits are the current
accounting calendar week. The format is YYWW (for example, 0225). The Country of Origin is the full name of the country
where assembly is completed (for example, Mexico). The Country of Origin may be abbreviated (for example, USA or CN) if
backside marking is not possible because of size restrictions. (Note 3)
A vendor-specified logo may appear below Brand line 3 (for example, ARM).
Note 3:
As long as the device form, fit, and function remain the same, the data in Brand lines 1-3 may change. For example, the Lot
Number and Lot Split Identifier may change; the Date Code and Country of Origin may change if Skyworks selects a
second assembly source.
