Key Features
- 1.8432 MHz HCMOS/TTL output oscillator capable of driving up to 10 TTL loads with a maximum fall time of 10 ns for clean digital timing signals
- Enable/disable control pin allowing the oscillator output to be gated by a logic signal, reducing power consumption when the clock is not needed
- Through-hole DIP-14/4 package providing robust board retention and easy manual or wave-solder assembly in prototype and low-volume production
Applications
The MXO45-3C-1M8432 is commonly used as a baud-rate clock source for UART and serial communication circuits, where 1.8432 MHz divides evenly into standard baud rates such as 9600 bps, 57600 bps, and 115200 bps. It also serves as a reference clock in legacy microprocessor systems and embedded controllers using 8051 or Z80 architectures that require a stable TTL-compatible oscillator. The enable/disable pin supports low-power modes in battery-operated embedded designs.

Frequently Asked Questions
Why is 1.8432 MHz a preferred oscillator frequency for UART baud-rate generation?
1.8432 MHz divides evenly by integer factors to produce standard UART baud rates: divided by 16 gives 115200 bps, by 32 gives 57600 bps, by 192 gives 9600 bps, and by 1920 gives 960 bps. This exact divisibility eliminates baud-rate error that would accumulate if an approximate frequency were used, ensuring reliable serial data framing in RS-232, RS-485, and TTL-level UART communications.
How many TTL loads can the MXO45-3C-1M8432 drive, and what is its output fall time?
The MXO45-3C-1M8432 drives up to 10 TTL loads at 50 pF with a maximum fall time of 10 ns. This output drive strength is sufficient for distributing the 1.8432 MHz clock to multiple UART peripherals or logic ICs on the same board without requiring a buffer, as long as the total capacitive load stays within the 50 pF specification per output.
How does the enable/disable pin on the MXO45-3C-1M8432 benefit low-power embedded system designs?
The enable/disable control pin allows the host microcontroller to gate the 1.8432 MHz clock output when serial communication is inactive. In duty-cycled IoT devices that wake for 10 ms per second to transmit data and then sleep, disabling the oscillator during the 990 ms sleep period can reduce system current by several milliamps, significantly extending battery life in coin-cell or AA-battery powered designs.
