FEATURES
OUTLINE & DIMENSIONS
XOF91 Oscillators
DESCRIPTION
XOF91 series oscillators are designed to provide very high quality
LVCMOS outputs at frequencies from 125MHz to 320MHz. A high Q
crystal and ultra-low jitter multiplier circuit provide extremely good
performance. An enable/disable function is standard and the
oscillator may also be specified with a power down function.
Frequency Range:
125.0MHz to 200.0MHz (15pF load)
125.0MHz to 320.0MHz (10pF load)
Output Logic:
LVCMOS
Integrated Phase Jitter:
0.4ps typical 0.5ps max
(12kHz ~ 20MHz) at 155.520MHz
Period Jitter RMS:
3ps typical, 5 ps max. at 155.520MHz
Period Jitter Peak to Peak:
20ps typ., 30ps max. at 155.520MHz
Frequency Stability

Supply Voltage:
+2.5 Volts ±5% or +3.3VDC ±5%
Output Voltage
High '1':
90% Vdd minimum
Low '0':

Start-up Time:
5ms typical, 10ms maximum
Duty Cycle:
50% ±5% (Measured at Vdd-1.3V)
Static Discharge Protection:
2kV maximum
Ageing:
±3pmm max. first year then ±2ppm
SPECIFICATION
PAD 1 OPTIONS
Permanent damage may occur if units are operated beyond
specified limits.
Supply Voltage:
+4.6 VDC max.
Input Voltage Vi:
Vss-0.5 min., Vdd +0.5V max.
Input Voltage Vo:
Vss-0.5 min., Vdd +0.5V max.
DISABLE
Output is disabled when enable/disable pad is
taken below 0.3 Vcc referenced to ground
Oscillator is continues to run.
ENABLE
Oscillator is enable when enable/disable Pad is
taken above 0.7 Vcc referenced to ground.
POWER DOWN
Available by special request: Oscillator shuts down
when disabled.
