• Environmental Screening Available
Model BXFS1045 2-18 GHz Synthesizer covers the S, C, X, and Ku-Bands, offers fast 65 µsec settling time, provides +13 dBm of
output power from the +/- 6 and +5 volt supply, and delivers low phase noise performance (-81 dBc/Hz @ 10 KHz Offset). API
Technologies offers flexibility to meet customer-specific requirements including options for input voltages, output power, and
frequency control.
Using a hermetic laser-welded package, the BXFS1045 is able to withstand extreme environmental conditions, and is
configurable for most military airborne and ground based applications. Able to provide outstanding performance at a wide
temperature range (-40°C to +85°C), the Synthesizer is ideally suited for military requirements and high-end commercial
applications such as microwave receivers, microwave telemetry systems, uplink communication platforms, instrumentation, and
military communication systems.

The subassembly shall use a 3-wire SPI-compatible local temperature
sensor capable of running with a Vcc ranging from 3.0V to 5.5V. All 3
SPI interface pins (clock, data, and select) and the Vcc pin shall be wired
out directly, and only, to the subassembly connector. The GND pin shall
be wired out directly, and only, to the subassembly connector. This
allows temperature to be read at all times regardless of power down
state or other subassembly power inputs. Vcc shall be bypassed to GND
with a 0.1uF capacitor. Part number MAX6630MUT is suggested
(http://www.maxim-ic.com/datasheet/index.mvp/id/2577/t/al). This
part is also available on tape & reel. If this part is used, it is suggested to
connect pin 2 (NC) to ground through a provisional resistor (initially
unpopulated) for compatibility with similar parts from other
manufacturers.
The temperature sensor interface signals will be static during RF
measurements.
Power monitor for 100 MHz reference output J9. Output shall be logic
“1” for output power > -5 dBm and logic “0” for output power < -10
dBm.
Power monitor for 100 MHz reference output J10. Output shall be logic
“1” for output power > +10 dBm and logic “0” for output power < +5
dBm.
Phase lock indicator for the synthesizer. Output shall be logic “1” when
the synthesizer has achieved phase lock, and logic “0” otherwise.
Power monitor for the synthesizer. Output shall be logic “1” for J1, J2,
J3, and J4 output power > +8 dBm and logic “0” for output power < +3
dBm.

Pins which are unused but reserved. To maintain compatibility with
future designs, these pins shall be left unconnected.
LVTTL Control Levels: Control inputs shall use 3.3V LVTTL logic levels. Each input
shall source or sink 0.5mA maximum. LVTTL low, or logic ‘0’, shall be 0.8 volts
maximum. LVTTL high, or logic ‘1’, shall be 2.0 volts minimum. Steady-state input
voltage shall be 0.0 volts minimum and 3.5 volts maximum.
LVTTL Output Levels: Outputs shall use 3.3V LVTTL logic levels. LVTTL low, or logic
‘0’, outputs shall be 0.5 volts maximum when sinking up to 2 mA. LVTTL high, or logic
‘1’, outputs shall be 2.4 volts minimum when sourcing up to 2 mA. Steady-state
output voltage shall be 0.0 volts minimum and 3.5 volts maximum.
