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
