Product Description
The FK Series 3.3V crystal clock oscillator
achieves superb stability and low power
consumption over a broad range of operating
conditions and frequencies. The low jitter
output clock signal, generated internally with
a non-PLL oscillator design, is compatible with
LVCMOS logic levels. The device, available on
tape and reel, is contained in a 3.2 x 2.5mm
surface-mount ceramic package.
Applications
Ideal for compact, high-density applications
requiring low power or tight stability, including:
Network adapter cards•
Portable Multimedia Devices•
Hard Disk Drives•
GPS/Navigation•
Bluetooth•
802.11a/b/g WiFi•
