Supply pin for the Rx PLL section. Allowable range
is 2.7 to 5.5 V and must be within 0.5 V of all other
V CC pins. Good bypassing is required and isolation
with a 10 Ω resistor is recommended.
Rx Phase Detector Output. The output either
sources or sinks current, or neither, depending on
the phase difference of the phase detector input
signals. During lock, very narrow pulses with a
frequency equal to the PLL reference frequency are
present. Output current is either 100 µA or
Ground pin for the PLL section. A direct connection
to a ground plane is strongly recommended.
Tx Phase Detector Output. Description same as for
Pin 4, except bit 1/20 controls the current level.
Supply pin for the Tx PLL section, MCU Serial
Interface, MCU Clock Counter, and the Reference
Oscillator. Allowable range is 2.7 to 5.5 V and must
be within 0.5 V of all other V CC pins. Good
bypassing is required and isolation with a 10 Ω
resistor is recommended.
Receives the signal from the external 64/65 or
128/129 prescaler. DC bias is at 1.5 V.
Modulus Control Output for the Tx PLL section. Can
be set to output in a current mode or a voltage
mode, selectable with bit 3/16.
400 µA, selectable with bit 2/20.
