Type

Description

Crystal connection or external frequency input. This pin has dual functions.

It can be connected to either an external crystal or an external reference

clock.

VSS

Ground to entire chip.

Digital logic input used to select Down (LOW) or Center (HIGH) spread

options. (Refer Output Frequency Deviation and Spread Option Selection

Table). This pin has an internal pull-up resistor.

D_C

Spread range select. Digital logic input used to select frequency deviation

(Refer Output Frequency Deviation and Spread Option Selection Table).

This pin has an internal pull-up resistor.

Spread spectrum clock output (Refer Input/Output Frequency Range

Selection Table and Output Frequency Deviation and Spread Option

Selection Table).

Frequency range select. Digital logic input used to select input frequency

range (Refer Input/Output Frequency Deviation and Spread Option

Selection Table). This pin has an internal pull-up resistor.

SRS

ModOUT

FRS

VDD

Power supply for the entire chip (3.3V).

Crystal connection. Input connection for an external crystal. If using an

external reference, this pin must be left unconnected.
