IQXO-22, -23 CLOCK OSCILLATORS
ISSUE 20; 1 NOVEMBER 2010 - RoHS 2002/95/EC
Not recommended for new designs
Description
▪Standard 8pin DIL 5.0V supply crystal oscillator
▪Available with or without a standby function
▪Crystal oscillator in an 8pin DIL package hermetically sealed
▪For parts that meet tougher environmental specications
please see our IQXO-35 and IQXO-36 range
▪For parts that meet tough environmental specications and
military temperature range please see our IQXO-85 and
IQXO-87
▪For individually screened parts that meet tough
environmental specications and military temperature range
please see our IQXO-86 and IQXO-88
▪Fast Make capability: CFPP-23 series programmable
oscillators are the nearest equivalent fast make model
Frequency Range
▪500kHz to 160MHz
Output Compatibility & Load
▪HCMOS/TTL
▪Drive Capability: 50pF max or 10TTL (<70.0MHz) 30pF max
(70.0 to 160.0MHz)
▪No Standby Operation (IQXO-22)
▪Standby Operation (IQXO-23)
Frequency Stabilities
▪±25ppm, ±50ppm, ±100ppm (over operating temperature
range)
Operating Temperature Ranges
▪ 0 to 70°C
▪–40 to 85°C
Storage Temperature Range
▪–55 to 125°C
Standby Operation (IQXO-23)
▪No connection or Logic ‘1’ to pin 1 enables oscillator output
▪Logic ‘0’ to pin 1 disables oscillator output; when disabled the
oscillator output goes to the high impedance state
▪Maximum ‘pull-down’ resistance required to disable
output = 20kΩ
▪Standby Current: 50µA typical
Environmental
▪Terminal Strength: 0.91kg max force perpendicular to top and
bottom
▪Hermetic Seal: Not to exceed 1x10-8 mBar litres of Helium
leakage
▪Solderability: MIL-STD-202E, Method 208C
▪ Vibration: 0.76mm displacement, 10Hz-55Hz, 1min in 3
mutually perpendicular planes, duration 2hrs each plane
