Description
Very low stability crystal oscillator in a hermetically sealed
ceramic package with a metal lid that achieves superior
perfomance compared with standard clock oscillators.
Frequency Parameters
Frequency
10.0MHz to 160.0MHz
Frequency Stability
±5.00ppm to ±20.00ppm
Frequency Stability (for ±10, ±15 and ±20ppm): Includes
frequency tolerance @ 25°C, operating temperature range,
supply voltage variation, load variation and 1st year's ageing
@ 25°C.
Frequency Stability (for ±5ppm): Includes frequency tolerance
@ 25°C and operating temperature range only.
Electrical Parameters
Supply Voltage
1.8V ±5%
Operating Temperature Ranges
-40 to 85°C
Output Details
Output Compatibility
HCMOS
Drive Capability
15pF max
Output Voltage Levels:
Output Low (VoL): 10%Vs max
Output High (VoH): 90%Vs min
Start Up Time (0V to Vs): 5ms max
Output Control
Enable/Disable Mode:
Logic '0' (30%Vs max) to pad 1 disables oscillator output, the
output goes to a high impedance state.
Logic '1' (70%Vs min) or no connection to pad 1 enables
oscillator output.
Noise Parameters
Period Jitter: 5ps typ @ 40MHz and 3.3V
Phase Jitter (12kHz to 20MHz): 0.4ps typ @ 40MHz and 3.3V
Phase Noise (typ @ 40MHz and 3.3V):
-67dBc/Hz @ 10Hz
-99dBc/Hz @ 100Hz
-125dBc/Hz @ 1kHz
-144dBc/Hz @ 10kHz
-151dBc/Hz @ 10kHz
-154dBc/Hz @ 1MHz
-156dBc/Hz @ 10MHz
Environmental Parameters
Storage Temperature Range: -55 to 125°C
Drop Test: dropped three times from a height of 30cm onto a
hard wooden board.
Vibration (MIL-STD-202F, Method 201A): frequency range
10~55Hz in X, Y and Z axes for 2 hours each (6 hours total).
