PNP-1090-P22
DESCRIPTION:
The PNP-1090-P22 is a complete low noise frequency syn-
thesizer, comprised of VCO, PLL, loop filter and data inter-
face. The PNP family of RF signal sources is the world’s
first truly configurable frequency synthesizer module. PNP
technology offers the designer the ability to configure all of
the synthesizer’s vital functions ‘on the fly’ with simple
strings of code that contain the commands of START,
STOP, STEP, CHANNEL and REF. When new data is re-
ceived, the PNP module optimizes its internal settings for
best overall integrated phase noise, switching speed and
spurious suppression, all automatically and in less than 100
µS. Therefore, if the system requires 100 kHz steps in
mode #1 and 1 MHz step size in mode #2, these smart syn-
thesizers can make quick adjustments with amazing accu-
racy, speed and performance.
Control of the internal registers is accomplished through a
serial data interface. Many industry standard protocols are
supported, including I2C, SPI, and MICROWIRE Serial In-
terfaces. The PNP-1090-P22 is powered from +3V and
+12.5V supplies delivering +7 dBm of RF output power.

FREQUENCY/CHANNEL
FIGURE 3: MULTIPLIER (DB24 - DB27) The data in FREQUENCY/CHANNEL (DB0-DB23) is multiplied
by 10n where the value of n is determined by the contents of MULTIPLIER (DB24-DB27) as shown below.

MULTIPLIER
FIGURE 4: FUNCTION SELECT (DB28 - DB31). After the data in FREQUENCY/CHANNEL (DB0 - DB23)
is multiplied by 10n where the value of n is determined by the contents of MULTIPLIER (Figure 3), it is then
routed internally to the START, STOP, STEP, REF or CHANNEL registers based on the contents of FUNC-
TION SELECT as shown below.

FUNCTION SELECT
0 0 0 0 CHANNEL. Routes data from DB0-DB23 to the CHANNEL REGISTER.
0 0 0 1 START. Routes data from DB0-DB23 to the START REGISTER.
0 0 1 0 STOP. Routes data from DB0-DB23 to the STOP REGISTER.
0 0 1 1 STEP. Routes data from DB0-DB23 to the STEP REGISTER.
0 1 0 0 REFERENCE. Routes data from DB0-DB23 to the REFERENCE REGISTER
All FUNCTION SELECT values not shown above are reserved for factory use.
