■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  
5MTYP (or selectable from 1.6k~  
8.4k)  
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
