The UF324/UF34 XO series is crystal oscillator
family optimized to save board space. The
series consists of high performance HCSL crystal
oscillators with ultra low jitter performance to
meet strict chipset requirements. It supports
various options including wider frequency range,
2.5V/3.3V voltage, and various stabilities. It is
designed to meet the clock source specifications
for communication systems, and other high
performance equipment.
