2795V

Crystal Clock Oscillator 2795 Series n Model name 2795V Frequency stability of ±100 x 10–6. Two Frequencies-switching Type n Application l For compact mobile information equipment, such as PDA and notebook PC n 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.
