CTS MXO45 and MXO45HS are legacy thru-hole clock oscillators that provide a cost-effective solution for older HCMOS/TTL applications. These oscillators feature a standard 14-pin or 8-pin metal DIP package, low phase jitter performance, and a frequency range from 1 to 200 MHz. While not recommended for new designs, they remain available to support existing applications developed for the full and half-size metal DIP packages. They are commonly used in computers, storage area networking, broadband access, microcontrollers/FPGAs, networking equipment, and test and measurement applications.
