EVALUATION BOARD HARDWARE
The evaluation board requires the use of an SDP-S motherboard
to program the device. This is not included and must be
purchased separately. The

POWER SUPPLIES
The board is powered from external banana connectors. The
voltage can vary between 6 V and 12 V. The power supply
circuit provides 3.0 V to V

circuit provides 3.0 V to V
DD
on the board (which supplies the
DD
and DV
DD
pins) and allows the user to choose
P
. The default settings are
3.0 V for the
DD
and 5 V for the
P
. Note
that V
DD
should never exceed 3.3 V. This can damage the device.
External power supplies can be used to directly drive the device.
In this case, the user must insert SMA connectors as shown in

INPUT SIGNALS
The necessary reference input comes from an on-board tempera-
ture compensated crystal oscillator (TCXO) of 25 MHz
frequency.
Alternatively, this can be sourced from an external generator. In
this case, remove R16 and R14 to disconnect the TCXO from
the supply and from the reference path, insert Connector J11 or
the edge mount connector, J5, and connect the external genera-
tor to the connector. A low noise, high slew rate reference
source is best for achieving the stated performance of the
ture compensated crystal oscillator (TCXO) of 25 MHz
frequency.

Digital SPI signals are supplied through the SDP connector, J1.
Using the SDP-S platform is recommended. The SDP-B can
also be used, but Resistor R57 must be removed on the SDP-B
board. Some additional spurious low frequencies may appear if
the SDP-B connector is used.

OUTPUT SIGNALS
All components necessary for LO generation are inserted on
board. The PLL is made up of the
board. The PLL is made up of the
synthesizer, a
passive loop filter, and the VCO. This board is supplied with a
VCO ROS1800+ from Mini-Circuits, which covers a frequency
range from 1700 MHz to 1800 MHz. A low-pass filter of 50 kHz
loop bandwidth is inserted between the charge pump output
and the VCO input. The 2.5 mA charge pump current setting
is used. The VCO output is available at RFOUT through a
standard SMA connector, J2. The MUXOUT signal can be
monitored at Test Point T8 or at SMA Connector J3.
