The MXO45-2C-4M9152 is a legacy HCMOS/TTL clock oscillator designed for thru-hole applications requiring low-cost, reliable timing solutions. It features a 14-pin metal DIP package with fundamental crystal design, operating at a nominal supply voltage of 5.0V (±10%) and supporting frequencies from 1 MHz to 200 MHz with ±50 ppm frequency stability. The device delivers low phase jitter performance (0.7 ps RMS typical) and HCMOS output with duty cycle of 45–55% at the 50% level, making it suitable for legacy HCMOS/TTL applications. Operating temperature range is -20°C to +70°C, with startup time of 5–10 ms. Common applications include computers, peripherals, networking equipment, and test and measurement systems where established thru-hole designs are maintained.
