NAME
DESCRIPTION
13
VCC_SYN
DC Power Supply for Synthesizer Circuits. Connect to a +3.3V low-noise supply. Bypass to GND with
a 1nF capacitor connected as close as possible to the pin. Do not share capacitor ground vias with
other ground connections.
14
XTAL
Crystal-Oscillator Interface. Use with an external parallel-resonance-mode crystal by a series 1nF
capacitor. See the
Typical Operating Circuit
.
15
REFOUT
Crystal-Oscillator Buffer Output. A DC-blocking capacitor must be used when driving external
circuitry.
16
VCC_DIG
DC Power Supply for Digital Logic Circuits. Connect to a +3.3V low-noise supply. Bypass to GND
with a 1nF capacitor connected as close to the pin as possible. Do not share capacitor ground vias
with other ground connections.
