MM Series 5.0 X 7.0 X 2.0 mm HCMOS/TTL
Compatible Miniature Surface Mount Oscillators
High Performance HCMOS/TTL
Compatible Surface Mount Oscillators
M-tron MM series quartz crystal oscillators offer
HCMOS technology and an AT-strip crystal in a
miniature ceramic surface mount package.
Output is TTL and HCMOS compatible. Tri-state
output is optional.
Electrical Specifications
Pin Connections
Because this product is based on AT-strip technology, not all frequencies in the range stated are available.
Contact the factory for availability of specific frequencies.

TTL load - See load circuit diagram #1 on page 137. HCMOS load - See load circuit diagram #2 on page 137.
3
Symmetry is measured at 1.4 V with TTL load, and at 50% Vdd with HCMOS load.
4
Rise/Fall times are measured between 0.5 V and 2.4 V with TTL load, and between 10% Vdd and 90% Vdd with HCMOS load.
See page 136, Figure 1 for suggested solder profile.

Tri-state Control Logic
Pin 1 high or floating: clock signal output.
Pin 1 low: output disabled to high impedance.
NOTE:
A capacitor of value 0.01
mF
or greater between Vdd
and Ground is recommended.
