Features
l
With the adoption of frequency-writing technology, even the tightest
delivery deadline can be met.
l
Two frequencies: switch from one to the other according to the input
voltage (high or low) of PAD #1.
l
PLL technology allows this crystal oscillator to support 1 to 125 MHz.
l
Automatic mounting by taping and IR reflow (lead-free) are possible.
l
Compact and light with the following dimensions and weight of 5.0 x 3.2 mm,
1.0 mm, and 0.06 g.
