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.
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.
The output buffer is 3-State and has a fanout of 10 - TTL.
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)
Oscillator Frequency : 4MHz ~ 70MHz
Divider Ratio
: Selectable from f0/1, f0/2, f0/4, f0/8
Output
: 3-State, 10 - TTL fanout
Operating Voltage Range
: 4.0V ~ 6.0V
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
