CFPS-31
ISSUE 2; 28 JULY 2005
Delivery Options
■ Please contact our sales office for current leadtimes
Description
■ The CFPS-31 is a 1.8V low voltage, surface mount
oscillator with a CMOS output
Output Compatibility
■ Tri-state CMOS
■ Drive Capability 15pF max
Package Outline
■ 7.5 x 5.0mm SMD Ceramic Package
Frequency Range
■ 1.8 to 160.0MHz
Frequency Stabilities
■ ±25ppm, ±50ppm, ±100ppm (inclusive of supply
voltage & output load variations over the operating
temperature range)
Operating Temperature Ranges
■ -10 to 70°C (CFPS-31)
■ -40 to 85°C (CFPS-31I)
Storage Temperature Range
■ -55 to 125°C
Tri-state Operation
■ Logic ‘1’ to pad 1 enables oscillator output (> 70% Vs)
■ Logic ‘0’ to pad 1 disables oscillator output; when the
oscillator output goes to the high impedance state
(< 30% Vs)
■ No connection to pad 1 enables oscillator output
■ Standby current 10
A max
Solder Conditions
■ For typical soldering conditions, please see the relevant
pages in Applications Notes
Marking
■ Model Number
■ Frequency
Minimum Order Information Required
■ Frequency + Model Number + Operating Temperature
Code (if applicable) + Frequency Stability
