CFPS-39
ISSUE 1; 19 OCTOBER 2004
Delivery Options
■ Please contact our sales office for current leadtimes
Description
■ The CFPS-39 is a 3.3V, ultra minature surface mount oscillator
with a HCMOS output
Output Compatibility
■ Tri-state HCMOS
■ Drive Capability 15pF max
Package Outline
■ 3.2 x 2.5mm SMD Package
Frequency Range
■ 1.80 to 50.0MHz
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-39)
■ -40 to 85°C (CFPS-39I)
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 disabled the
oscillator output goes to the high impedance state (<30% Vs)
■ No connection to pad 1 enables oscillator output
Solder Conditions
■ For typical soldering conditions, please see the relevant
pages in Applications Notes
Marking
■ Frequency
Minimum Order Information Required
■ Frequency + Model Number + Operating Temperature
Code (if applicable) + Frequency Stability
