OSCILLATORS
5.0V surface mount oscillator in a ceramic package, with a
hermetically sealed metal lid
Please see CFPP-12 series Programmable Oscillators for
nearest equivalent fast make parts
5 x 3.2mm
1.8 to 50MHz
Tri-state HCMOS (5.0V)
Drive Capability 50pF / 10TTL max
±25ppm, ±50ppm, ±100ppm (inclusive of supply voltage and
output load variations over the operating temperature range)
–
10 to 70°C (CFPS-12)
–
40 to 85°C (CFPS-12I)
–55 to 125°C
Logic ‘1’ (>2.2V) to pad 1 enables oscillator output
Logic ‘0’ (<0.8V) to pad 1 disables oscillator output; when
disabled the oscillator output goes to the high impedance
state
No connection to pad 1 enables oscillator output
Logic ‘1’ = 4.5V min, IOH –16mA max
Logic ‘0’ = 0.5V max, IOL 16mA max
Fast Make Capability
