M1280 Series
Crystal Oscillators HCMOS/TTL 5V
Thru-Hole/Gull Wing; Commercial: 0° to 70°
Fixed Frequency, 1 KHz to 175 MHz
Features
Frequency from 1 KHz to 175 MHz
Choice of thru-hole packages
Description
DIL Full Size (“M”)
Valpey Fisher’s thru-hole oscillators
embody 25 years of design and
Half Size DIL (“H”)
Gull Wing SMD
manufacturing know-how. They are
available in full –size and half size
packages, all hermetically sealed with
welded stainless steel cover. These 5V
thru-hole oscillators are designed for
everyday stresses of 0°C to 70°C
operation and extended frequency
selection of 1 KHz to 175 MHz. Higher
(5V) operation ensures superior output
loading and faster rise/fall times
characteristics.
Tristate and “Hard Zero” options accommodate ATE
Very low power when tristated
Start up time less then 5 ms
Stability options from +/-100 ppm to +/- 20 ppm
Guaranteed start-up with ramping DC Supply
45/55 symmetry available
Internal bypass capacitor delivers superior waveform
characteristics
Jitter from positive edge to positive edge is 50 ps RMS max
Typical Applications
Any thru-hole PCB that requires a standard HCMOS/TTL
5V clock, including microprocessors and microcontrollers
