■General Description

■Features

The XC2151 series are a group of high frequency, CMOS low power

crystal oscillators with oscillator & divider circuitry, oscillator capacitors

and amplifier feedback resistors built-in.

High Precision

: Built-in oscillator capacitors

16pF TYP (or selectable from 10 ~ 20pF)

: On-chip amplifier feedback resistor

5MΩ TYP (or selectable from 1.6kΩ ~

8.4kΩ)

An oscillator circuit can be created from just an external crystal.

Output frequency can be selected from four frequencies :

Fundamental f0/1, Divided f0/2, f0/4, f0/8.

Oscillator Frequency: 4MHz ~ 70MHz

Divider Ratio

Output

Operating Voltage Range

: 4.0V ~ 6.0V

: Selectable from f0/1, f0/2, f0/4, f0/8

: 3-State, 10 - TTL fanout

The output buffer is 3-State and has a fanout of 10 - TTL.

Small Quiescent Current

Stand-By Function

Low Cost

: Oscillator circuit can be created from just

an external crystal

Ultra Small Package : SOT-26 (150mW) mini mold
