| EURO QUARTZ Miniature 7.0 x 5.0 x 1.4mm hermetically-sealed package Frequency Range 500kHz to 125MHz Tristate (Enable/Disable) function as standard Supply voltage range 1.8, 2.5, 3.3 or 5.0 Volts XO91 Series Oscillators 7 x 5mm SMD HCMOS Page 1 of 2 OUTLINE & DIMENSIONS DESCRIPTION XO91miniature oscillators consist of a TTL/CMOS-compatible hybrid circuit together with a miniature quartz crystal packaged in a lowprofile, industry-standard ceramic package. The high quality design and materials employed provide a highly reliable clock oscillator in a miniature package while mass production methods ensure that the XO91 provides a cost-effective oscillator solution. SPECIFICATION Frequency Range: Supply Voltage: Output Logic: Frequency Stability* Temperature Range 0 to +50C: -20 to +70C: -40 to +85C: -55 to +105C: Rise/Fall Time: Output Voltage: HIGH `1': LOW `0': Output Load CMOS: TTL: Duty Cycle: Supply Current: Operating Temperature 500kHz to 125.0MHz 1.8, 2.5, 3.3 or 5.0 Volts 10% HCMOS/LSTTL Stability from 10ppm from 15ppm from 25ppm from 100ppm see table 90%Vdd minimum 10%Vdd maximum 15pF (50pF available) 10 LSTTL loads 50%5% typical See table 0~50C (Light Commercial) 0~70C (Commercial) -40~+85 (Industrial) -55~+105C (Military) -55~+105C 5ms max. 10ms max. (to reach 90% amplitude at 252C) 5ppm max. In first year <1ps typical 100ms max. 100ns max. Storage Temperature: Startup Time 500kHz to 32MHz: 32MHz+ to 125MHz: SOLDER TEMPERATURE PROFILE Ageing: Phase Jitter RMS: Enable Time: Disable Time: Tristate Function (Pad 1): Output (Pad 3) is active if Pad 1 is not connected or a voltage to Pad 1 is 'HIGH'. Output is high impedance when 'LOW' or GROUND is applied to Pad 1. * Frequency stability is inclusive of calibration tolerance at 25C, frequency change due to shock & vibration, 10 supply voltage variation and stability over temperature range. Note: Parameters are measured at ambient temperature of 25C, supply voltage as stated and a load of 15pF CURRENT CONSUMPTION & RISE/FALL TIME Frequency Range 500kHz to 32MHz 32MHz+ to 50MHz 40MHz+ to 125MHz Supply Voltage (10%) +1.8V 8mA 10mA 25mA +2.5V +3.3V +5.0V 10mA 14mA 30mA 15mA 25mA 16.5mA 35mA 35mA 40mA Rise/Fall Time 4ns max. 3ns max. 2ns max.
