FEATURES
Description
• Jitter from positive edge to positive edge is 6 ps RMS maximum, ensuring stable data transmission
• Stability options of ±100 ppm and ±50 ppm
• 45/55 symmetry is standard
• Guaranteed start-up with ramping DC Supply
• Start up time less than 5 ms
MF Electronics R-Series surface mount
(SMD) oscillators provide clock wave-
forms needed to clock standard HCMOS
or TTL circuits.
• Tristate option available
• Very low power when tristated
TYPICAL APPLICATIONS
• Telecom and data networking applications that require low jitter, including:
– DSL
– Gigabit ethernet
– Fibre Channel
– VoIP
