HCMOS/TTL 3.3V

5 x 7 mm Surface Mount

Industrial: -40ºC to +85ºC

FIXED/ TRISTATE, 500 KHz to 125 MHz

FEATURES

Description

• Industrial operating temperature range from -40º to +85ºC accomodates rugged environments

• Low jitter of 6 ps rms max ensures stable data transmission

• Stability options of ±100 ppm to ±25 ppm

• 45/55 symmetry is standard

• Guaranteed start-up with ramping DC Supply

• Start up time less than 5 ms

MF Electronics R-Series industrial

temperature range surface mount (SMD)

oscillators provide clock waveforms

needed to clock standard HCMOS

or TTL circuits in PCBs mounted in

rugged environments.

• Tristate option standard

• Very low power when tristated

TYPICAL APPLICATIONS

• Telecom and data networking applications that require low jitter and are subjected to rugged

environmental conditions, including:

– DSL

– Gigabit ethernet

– Fibre Channel

– VoIP
