| Voltage Controlled Crystal Oscillators (VCXO's) S-Type Description: The S-Type is a high volume, high reliability CMOS VCXO. It is ASIC based and available in a through-hole or SMD industry standard footprint ceramic package. Features: * Frequencies to 65.536 MHz * 5 or 3.3 volt operation * <6 ps rms jitter (output frequencies >12 MHz) * Advanced custom ASIC technology * Surface mountable * TTL or CMOS selectable * Tri-state output * 0/70C or -40/85C Operating Temp.

TTL logic low disables output. TTL logic high or no connection enables output frequency. Circuit and case ground Output waveform TTL logic low provides waveform symmetry for CMOS. TTL logic high or no connection provides waveform symmetry for TTL.
