FEATURES
Description
• Fixed frequency or Tristate
• Very low power when tristated
• Frequency from 1 KHz to 175 MHz
• Start up time less than 5 ms
• Stability options from ±100 ppm to ±20 ppm
• Guaranteed start-up with ramping DC Supply
• 45/55 symmetry available
MF Electronics T-series surface mount
(SMD) oscillators provide clock wave-
forms needed to clock standard HCMOS
or TTL circuits.
TYPICAL APPLICATIONS
• Any surface mount PCB that requires a standard HCMOS/TTL 5V clock, including microprocessors
and microcontrollers.
