SM77D Series 3.3 V

CMOS Clock Oscillators

Feb 2008

• Pletronics’ SM77D Series is a quartz crystal

controlled precision square wave generator with a

CMOS output.

• 70 to 180 MHz

• 5 x 7 mm LCC Ceramic Package

• Enable/Disable Function

• 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.

• Disable function includes low standby power

mode

• 3^rdOvertone Crystals used

• Improved circuit to minimize oscillator issues

such as multi-mode output signal.

• Low Jitter

• Capable of driving up to 50pF capacitive loads
