CFPS-32 SMD CLOCK OSCILLATORS
ISSUE 4; 1 NOVEMBER 2008 - RoHS 2002/95/EC
Description
2.5V surface mount oscillator in a ceramic package, with a
hermetically sealed metal lid
Package Outline
7 x 5mm
Frequency Range
1.8 to 160MHz
Output Compatibility & Load
Tri-state CMOS
Drive Capability 15pF max
Frequency Stabilities
±25ppm, ±50ppm, ±100ppm (inclusive of supply voltage and
output load variations over the operating temperature range)
Operating Temperature Ranges
–10 to 70°C (CFPS-32)
–40 to 85°C (CFPS-32I)
Storage Temperature Range
–55 to 125°C
Tri-state Operation
Logic ‘1’ (> 70% Vs) to pad 1 enables oscillator output
Logic ‘0’ (< 30% Vs) to pad 1 disables oscillator output;
oscillator output goes to the high impedance state
No connection to pad 1 enables oscillator output
Standby Current
10µA max
Start-Up Time
10ms max
Environmental
Shock: MIL-STD-202F, Method 213B (1000G, 0.5ms, 1/2
