SC-A1470 Series
PRELIMINARY
Description
The
SC-A1470 Series
of quartz crystal oscillators provide enable/disable 3-state LVCMOS compatible
signals for bus connected systems. Supplying Pin 1 of the SC-A1470 units with a logic 鈥?" or open enables
its Pin 3 output. In the disable mode, Pin 3 presents a high impedance to the load.
Features
鈥?Wide freqency range: 4.0MHz to 20.0MHz
鈥?User specified tolerance 鹵100ppm
鈥?Will withstand vapor phase temperatures of 253擄C
for 4 minutes maximum
鈥?Space-saving alternative to discrete component
oscillators
鈥?High shock resistance, to 1000g
鈥?Low Jitter - Wavecrest jitter characterization
