Product Description
The S1615 Series is a 5V 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 CMOS/TTL
logic levels. The device, available on tape and reel,
is contained in a 5x7mm surface-mount ceramic
package.
