CFPS-302, 303 CLOCK OSCILLATORS
ISSUE 5; 20 NOVEMBER 2008 - RoHS 2002/95/EC
Description
8-pin DIL compatible resistance welded enclosure,
hermetically sealed with glass to metal seal
Fast Make Capability
Please see CFPP-303 series Programmable Oscillators for
nearest equivalent fast make parts
Package Outline
8-pin DIL
Frequency Range
500kHz to 125MHz
Output Compatibility & Load
HCMOS/LSTTL
Drive Capability 15pF max or 10LSTTL
Non tri-state (CFPS-302)
Tri-state (CFPS-303)
Frequency Stabilities
±25ppm, ±50ppm, ±100ppm
(over operating temperature range)
Operating Temperature Range
0 to 70°C (CFPS-302, -303)
–40 to 85°C (CFPS-302I, -303I)
Storage Temperature Range
–55 to 125°C
Tri-state Operation (CFPS-303, -303I)
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
Disable current 50µA typical
Environmental

Vibration: 10 to 55Hz 0.76mm displacement, sweep 60
seconds, duration 2 hours
Rapid Change of Temperature over Operating
Temperature Range: 10 cycles
Shock: 981m/s2 for 6ms, three shocks in each direction along
the three mutually perpendicular planes
