APPLICATIONS INFORMATION
BASIC CONNECTIONS
The basic circuit connections for a typical ADRF6801 application
are shown in Figure 40.
SUPPLY CONNECTIONS
The ADRF6801 has several supply connections and on-board
regulated reference voltages that should be bypassed to ground
using low inductance bypass capacitors located in close proximity
to the supply and reference pins of the ADRF6801. Specifically
Pin 1, Pin 2, Pin 9, Pin 10, Pin 17, Pin 22, Pin 27, Pin 29, Pin 34,
and Pin 40 should be bypassed to ground using individual bypass
capacitors. Pin 40 is the decoupling pin for the on-board VCO
LDO, and for best phase noise performance, several bypass
capacitors ranging from 100 pF to 10 μF may help to improve
phase noise performance. For additional details on bypassing the
supply nodes, see the evaluation board schematic in Figure 42.
SYNTHESIZER CONNECTIONS
The ADRF6801 includes an on-board VCO and PLL for LO
synthesis. An external reference must be applied for the PLL to
operate. A 1 V p-p nominal external reference must be applied
to Pin 6 through an ac coupling capacitor. The reference is
compared to an internally divided version of the VCO output
frequency to create a charge pump error current to control and
lock the VCO. The charge pump output current is filtered and
converted to a control voltage through the external loop filter
that is then applied to the VTUNE pin (Pin 39). ADIsimPLL
can be a helpful tool when designing the external charge pump
loop filter. The typical Kv of the VCO, the charge pump output
current magnitude, and PFD frequency should all be considered
when designing the loop filter. The charge pump current magnitude
can be set internally or with an external RSET resistor connected to
Pin 5 and ground, along with the internal digital settings applied to
the PLL (see the Register 4—Charge Pump, PFD, and Reference
Path Control section for more details).
