Crystal Clock Oscillator

Two Frequencies-switching Type

2795 Series

Model name

–6

2795W Frequency stability of ±±11 ꢀ ±1 .

Application

For compact mobile information equipment, such as PDA and notebook PC

Features

With the adoption of frequency-writing technology, even the tightest

delivery deadline can be met.

Free

Two frequencies: switch from one to the other according to the input

voltage (high or low) of PAD #±.

PLL technology allows this crystal oscillator to support ± to ±25 MHz.

Automatic mounting by taping and IR reflow (lead-free) are possible.

Compact and light with the following dimensions and weight of 5.1 ꢀ 3.2 mm,

±.1 mm, and 1.16 g.

Absolute maꢀimum rating

Power supply voltage (V ) -1.5 to +7.1V DC

Storage temperature range -55 to +±25°C
