Fixed Frequency Crystal Oscillator (XO) The F-Type Fixed-Frequency Crystal Oscillator (XO) is a hybrid clock oscillator designed for use in both CMOS and TTL applications. It is available in either commercial or industrial temperature ranges and can be ordered with a 3-state option. The 3-state option allows the output of the oscillator to be placed in a high-impedance state for board-level testing by automatic testing equipment. The F-Type XO is also available in a surface-mount configuration. The pin through-hole version is compatible with a 14-pin DIP footprint. Typical applications for the F-Type oscillator are to provide clock signals for digital signal processing chips and microprocessors. Tight stabilities compatible with SONET and STRATUM 4 telephony requirements are available.
