MEMS Oscillator:
Introduction: MEMS Oscillators are timing devices
that generate highly stable reference frequencies. They
can be programmed for any signaling level such as LVPECL,
LVDS, CML, HCSL, LVCMOS, etc. MEMS Oscillators are said
to offer 10x more robustness and reliability than quartz
crystal oscillators. They feature up to 70kG and 50kG shock
vibrations, eliminates any start-up issues and frequency
dips when compared to quartz crystal oscillators.
Key Specifications:
Output Compatibility: Single-ended, differential or
differential + single-ended
Examples:
LVDS (Low Voltage Differential Signaling)
LVPECL (Low Voltage Positive Emitter Coupled Logic)
HCSL (High Speed Current Steering Logic)
CML (Current Mode Logic)
LVDS (Low Voltage Differential Signaling)
Frequency Range: The range of frequencies for which
the oscillator works.
Temperature Stability: Refers to how much the oscillator
frequency varies over the operating temperature range of
the device.
Note: The stability rating between 20 to 100 PPM is required
in applications such as consumer electronics, microprocessor
based clocking and multi-protocol serial interfaces, while
a rating of less than 50 PPM is chosen for telecom, broadband,
video and instrumentation applications.
Jitter Performance: Period jitter describes how
much any period may deviate from the ideal clock period
and is used to determine the setup/hold time margin within
a digital system. It is related to phase noise and a low
noise output stage is required to achieve good period of
jitter performance.
