| EURO QUARTZ FEATURES * * * * * * Industry-standard 7.0 x 5.0mm package Frequency Range 125MHz to 260MHz High frequency range at low cost Supply voltage 2.5V or 3.3Volts Ultra-low phase noise and jitter Tristate function to conserve power XOA91 Series Oscillators 7 x 5mm High Frequency Low Jitter HCMOS Clock Oscillator OUTLINE & DIMENSIONS DESCRIPTION XOA91 series oscillators are designed to provide an ultra-low phase noise and loww jitter HCMOS output at high frequencies from 125MHz to 260MHz. An enable/disable function is standard and the oscillator may also be specified with a power down function. SPECIFICATION Frequency Range: Output Logic: Phase Jitter: RMS Period Jitter: Frequency Stability Commercial: Industrial: Input Voltage: Output Voltage High '1': Low '0': Rise/Fall Time: Current Consumption: Load: Start-up Time: Duty Cycle: Input Static Discharge Protection: Ageing: 125.0MHz to 260.0MHz HCMOS 0.2ps typical 2.5ps typical 25ppm to 100ppm -10 to +70C 25ppm to 100ppm -40 to +85C +2.5V to +3.3VDC 10% +2.97V minimum +0.33 V maximum 0.25ns typical, 0.5ns max. (20%Vdd to 80%Vdd) 80mA typical (Frequency dependent) 15pF 5ms typical, 10ms maximum 50% 5% (Measured at Vdd-1.3V) 2kV maximum 2pmm per year maximum SOLDER TEMPERATURE PROFILE ABSOLUTE MAXIMUM RATINGS 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. PART NUMBER SCHEDULE Example: 250.00MHz XOA91050UCTB * Frequency Series Designation XOA91 Stability 100 = 100ppm 050 = 50ppm 025 = 25ppm Output Universal Operating Temp. Range C = Commercial (-10~70C) I = Industrial (-40~+85C) Output Option T=Tristate (enable/disable) P= Powerdown* Supply Voltage A = 3.3 Volts B = 2.5 Volts TRISTATE DISABLE Output is disabled when Pad 1 is taken below 0.3 Vcc referenced to ground Oscillator is continues to run. Oscillator is enable when Pad 1 is taken above 0.7 Vcc referenced to ground. Available by special request: Oscillator shuts down when disabled.
