Product Description
The S1633 Series is a 3.3V crystal clock oscillator
that achieves superb jitter and stability over a broad
range of operating conditions and frequencies. The
output clock signal, generated internally with a non-PLL
oscillator design, is compatible with LVCMOS/LVTTL
logic levels. The device, available on tape and reel,
is contained in a 3.2x5mm surface-mount ceramic
package.
