This document describes the specification for the
IDTF1370 Digital Pre-Distortion Demodulator for PA
linearization. This series of devices is offered in 2
variants to cover common UTRA bands. See part
number matrix below for additional detail.
COMPETITIVE ADVANTAGE
In typical basestation transmitters digital pre-distortion is
employed to improve the Transmitter performance. The
signal coming out of the PA is sampled and the incoming
Tx chain I&Q data is pre-distorted to counteract the
distortion inherent in the PA. The PA signal is adjusted
via a digital step attenuator to a lower level and then
sub-sampled at an IF frequency of ~200 MHz which
necessitates the need for a highly linear demodulator to
downmix to quadrature IF from the Transmit frequency.
By sampling IF_I and IF_Q independently and then
digitally combining these signals, an effective doubling of
the sample rate can be achieved. Any distortion in this
path will degrade the performance of the DPD algorithm.
By utilizing an ultra-linear demodulator w/integrated DSA
such as the IDTF1370, the ACLR and/or power
consumption of the full Tx system can be improved
significantly.

POWER-ON SEQUENCE
PRELIMINARY DATASHEET
The power-on sequence ensures F1370 works in default mode once powered on. If the F1370 is programmed after
applying DC power, the following power-on sequence is not needed. Note: To use power on sequence, SW_LATCH
cannot be grounded permanently.
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 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:
PRELIMINARY DATASHEET
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.

F1370 ATTENUATION TABLE
PRELIMINARY DATASHEET
The F1370 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 F1370, 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 F1370 in its minimum attenuation state. Likewise, data
words of either H66, HE6, or H67 (binary “01100110” or “11100110” or “01100111”) will place the F1370 in its
maximum attenuation state of 25.5 added attenuation.

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
writes to ENb (Standby) and RF SW bits (A0, A2).

GND
Ground these Pins.
3
RF_INY
Alternate RF Input. Separated from RF_INX by internal SP2T.
AC couple to this pin. Internally matched to 50 ohms
9, 16, 25
VCC
Power Supply. Bypass to GND with capacitors shown in the
Typical Application Circuit as close as possible to pin.
10
LO_ADJ
Connect the specified resistor from this pin to ground to set the
LO path ICC. This IS a current setting resistor
12
LO_IN
LO Input. AC couple to this pin. Internally matched to 50 ohms
7,13, 29
N.C.
No Connection. Not internally connected. OK to connect to Vcc.
Recommended Connection is Ground
14
STBY
STBY Mode. Pull this pin high for Standby mode (30mA). Pull
low or Ground for normal Operation

Connect the specified resistor from this pin to ground to set the
IF amplifier bias reference. This is NOT a current setting resistor
In-Phase Mixer Differential IF Output. Connect pullup inductors
from each of these pins to VCC (see the Typical Application
Circuit).
Quadrature Mixer Differential IF Output. Connect pullup
inductors from each of these pins to VCC (see the Typical
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.

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.
