IDTF1320 Digital Pre-Distortion Demodulator for PA Wide RF and LO BWs (~ 0.8 GHz)
linearization. This device is one of 2 variants to cover Ideal for Multi-Carrier Systems

COMPETITIVE ADVANTAGE Excellent ACLR performance
200 output impedance
In typical basestation transmitters a digital pre-distortion Fully integrated DPD demodulator
loop is employed to improve the Transmitter 6x6 36 pin package
performance. The signal coming out of the PA is Standby Mode w/Fast Recovery
sampled so that the I&Q data at Baseband can be pre- ICC: 262 mA
distorted before being sent to the Tx DAC to counteract
the distortion inherent in the downstream PA. The signal DEVICE BLOCK DIAGRAM
coupled from the PA is adjusted via a digital step
attenuator to a lower level and then sub-sampled at an CSb SDI CLK
IF frequency of ~200 MHz which necessitates the need
for a highly linear demodulator to downmix to SPI DEC
quadrature IF from the Transmit frequency. By
sampling IF_I and IF_Q independently and then digitally IFI
combining these signals, an effective doubling of the
sample rate can be achieved. Any distortion in this path SPLIT
will degrade the performance of the DPD algorithm. By
utilizing an ultra-linear demodulator w/integrated DSA STBY
such as the IDTF1320, the ACLR and/or power
consumption of the full Tx system can be improved Bias ISET
significantly.

POWER-ON SEQUENCE
The power-on sequence ensures F1320 works in default mode once powered on. If the F1320 is programmed after
applying DC power, the following power-on sequence is not needed.
The power-on sequence should be:
1. CSb & SW_LATCH must be set low at power-on
2. Once powered on, first set SW_LATCH high, then set CSb high
3. Proceed with normal programming.
The default state after using power-on sequence:
Maximum attenuation
RF_INX, LO_INA selected
Normal operation (not Standby Mode)
SERIAL PROGRAMMING
The device is programmed via the serial port by asserting Chip Select (CSb). Note: Most-Significant-Bit first,
where the Address Word is the Most-Significant-Byte.

TO PROGRAM THE SERIAL INTERFACE:
If CSb is de-asserted (set to high), the serial interface will ignore the CLK line. Once CSb is asserted (set to low), the
serial interface will recognize the CLK and any data present on DATA will be clocked into the registers with each
rising CLK edge. After the 16th CLK cycle, and before the 17th CLK cycle, CSb must be de-asserted to successfully
program the part with the desired bytes. If CSb is de-asserted before the 16th CLK cycle, or after the 17th CLK cycle,
there is no guarantee that the correct bytes will be programmed and the user will have to re-program the interface in
accordance with the aforementioned procedure.
SW_LATCH PROGRAMMING SEQUENCE
When SW_LATCH is pinned high during the programming sequence, "RFSW" and "ENb" registers cannot be
programmed and therefore will not toggle.
If SW_LATCH is pinned low during the programming sequence, the "RFSW" and "ENb" register will
toggle. This can be prevented with the "Programming Sequence" below.

4) With SW_Latch = 0, set CSb = 1
5) Set SW_Latch = 1

F1320 ATTENUATION TABLE
The F1320 gain/attenuation setting is controlled by 6 bits in the data word. The device provides an added attenuation
range from 0 dB to 25.5 dB in 0.5 dB steps. A "high" or "1" bit corresponds to attenuation stepped IN, while a "low" or
"0" bit corresponds to attenuation stepped OUT.

Because the first and last bits of the Data Word are not presently used by the F1320, two additional hex character
pairs exists for each of those in this table. For example, data words of either H00, H80, or H01 (binary
"00000000," "10000000," or 00000001) will place the F1320 in its minimum attenuation state. Likewise, data
words of either H66, HE6, or H67 (binary "01100110" or "11100110" or "01100111") will place the F1320 in its
maximum attenuation state of 25.5 added attenuation.

PIN DESCRIPTIONS
Pins Name Function
1 SW_LATCH Stand-by latch. Pull Low or Ground for Normal Operation. If left
floating, this input will be internally pulled high, disabling SPI

Alternate RF Input. Separated from RF_INX by internal SP2T.
3 RF_INY AC couple to this pin. Internally matched to 50 ohms
7 LO_INB LO Input B. AC couple to this pin. Internally matched to 50
ohms. Selected via SPI port.
9, 16, 25 VCC
10 LO_ADJ Power Supply. Bypass to GND with capacitors shown in the
12 LO_INA Typical Application Circuit as close as possible to pin.
13, 29 N.C. Connect the specified resistor from this pin to ground to set the
LO path ICC. This IS a current setting resistor
14 STBY LO Input A. AC couple to this pin. Internally matched to 50
17, 18 IF_BIAS_I ohms. Selected via SPI port.
19, 20 IF_BIAS_Q
No Connection. Not internally connected. OK to connect to Vcc.
IF_I+, IF_I- Recommended Connection is Ground
23, 24 IF_Q-, IF_Q+ STBY Mode. Pull this pin high for Standby mode (30mA). Pull
low or Ground for normal Operation
26 CSb
Connect the specified resistor from this pin to ground to set the
27 DATA IF amplifier bias reference. This is NOT a current setting resistor
In-Phase Mixer Differential IF Output. Connect pullup inductors
28 CLK from each of these pins to VCC (see the Typical Application
Circuit).
35 RF_INX Quadrature Mixer Differential IF Output. Connect pullup
inductors from each of these pins to VCC (see the Typical
-- EP Application Circuit).
Chip Select Bar. The falling edge initiates a programming cycle
and the rising edge latches the programmed shift register data
into the active register.
Serial Data Input
Serial Clock Input
Main RF Input. Separated from RF_INY by internal SP2T. AC
couple to this pin. Internally matched to 50 ohms
Exposed Pad. Internally connected to GND. Solder this exposed
pad to a PCB pad that uses multiple ground vias to provide heat
transfer out of the device into the PCB ground planes. These
multiple via grounds are also required to achieve the noted RF
performance.

control pins listed.

POWER SUPPLIES
All supply pins should be bypassed with external capacitors to minimize noise and fast transients. Supply noise can
degrade noise figure and fast transients can trigger ESD clamps and cause them to fail. Supply voltage change or
transients should have a slew rate smaller than 1V/20uS. In addition, all control pins should remain at 0V (+/-0.3V)
while the supply voltage ramps or while it returns to zero.
