Description
s
The CFPS-36 is a 1.8V surface mount, low voltage oscillator with
a CMOS output
Output Compatibility
s
Tri-state CMOS
s
Drive Capability 15pF max
Package Outline
s
5.0 x 3.2mm SMD Ceramic Package
Frequency Range
s
1.8 to 50.0MHz
Frequency Stabilities
s
±25ppm, ±50ppm, ±100ppm
(inclusive of supply voltage & output load variations over the
operating temperature range)
Operating Temperature Ranges
s
-10 to 70°C (CFPS-36)
s
-40 to 85°C (CFPS-36I)
Storage Temperature Range
s
-55 to 125°C
Tri-state Operation
s
Logic ‘1’ to pad 1 enables oscillator output (>70% Vs)
s
Logic ‘0’ to pad 1 disables oscillator output: when the oscillator
output goes to the high impedance state (<30% Vs)
s
No connection to pad 1 enables oscillator output
