Evaluation Board For PLL
Frequency Synthesizer
a
EVAL-ADF4213EB1
GE NE RAL D E SC RIP T IO N
FEATURES
Self-Contained Board including Synthesizer, VCO,s and
Loop Filter
Channel Spacing: 200kHz
T his board is designed to allow the user to evaluate the
performance of the ADF4213 Frequency Synthesizer for
PLL's (Phase Locked Loops). T he block diagram of the
board is shown below. It contains the ADF4213 synthe-
sizer, a pc connector, T CXO reference input, power
supplies and IF/RF outputs. Both output channels have a
20kHz loop filter. T he IF channel has a 540MHz VCO
while the RF channel has a 900MHz VCO. A cable is
included with the board to connect to a pc printer port.
RF Output: 900MHz
IF Output:
540MHz
Designed for 20kHz loop bandw idth on both IF and RF
Accom panying Softw are allow s com plete control of synthe-
sizer functions from PC
Battery Operated: Choice of 3V or 5V supplies
Typical Phase Noise Perform ance of -91dBc/ Hz @ 1kHz
offset for RF (900MHz)
T he package also contains windows software to allow
easy programming of the synthesizer.
Typical Spurious Perform ance of better than -90dBc at
200kHz offset from carrier
