SM77D Series 2.5 V
CMOS Clock Oscillators
January 2011
Pletronics’ SM77D Series is a quartz crystal
controlled precision square wave generator with a
CMOS output.
The SM77D series will directly interface TTL
devices also.
The package is designed for high density surface
mount designs.
This is a low cost mass produced oscillator.
Tape and Reel or cut tape packaging is available.
