Description
The
PT7C5024
series
are
fundamental
crystal
oscillator module ICs. They feature an oscillator circuit
with built-in capacitors with excellent frequency
response and an output buffer with high output drive
capability. They are available in miniature 6-pin
packages, making them ideal as DIP-type crystal
oscillators.

Note:
The operating frequency is a yardstick value derived form the crystal used for PTI characteristics authentication. However,
the oscillator for frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics
and mounting conditions, so the oscillation of components must be carefully evaluated. (See
Recommended Operating Conditions
in Page 3 .)

Block Diagram
Note:
The PT7C5024 series reduce crystal current by limiting driving current of oscillating-stage inverter and inhibiting
oscillating amplitude. Depending on the characteristics of using crystal or the mounting conditions, they may not oscillate
normally. Please evaluate the oscillation start-up characteristics adequately with your actual device. When this device is used for
buffer application, please pay attention to input amplitude to the XT pin. If it’s low input amplitude, the PT7C5024 series may not
operate normally.
Function Description
When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance.
