Key Features
- 18.432 MHz operating frequency ideal for standard UART baud rate generation (e.g., 115200, 9600 baud) with minimal clock error
- Enable/disable function allows power management and selective activation of the oscillator output in multi-clock systems
- HCMOS/TTL output with 8 ns maximum fall time ensures compatibility with a broad range of logic families and high-speed interfaces
Applications
The CB3LV-3I-18M4320 is primarily used in serial communication systems where 18.432 MHz is the standard clock frequency for UART baud rate generation, supporting standard rates from 1200 to 921600 baud with zero error. It is also deployed in network equipment, industrial controllers, and embedded microprocessor systems that require a stable, logic-compatible oscillator with enable control for low-power modes. The surface mount package facilitates automated assembly in compact communication interface boards.

Frequently Asked Questions
Why is 18.432 MHz the preferred clock frequency for UART communication systems?
18.432 MHz divides evenly by common UART baud rate divisors, producing exact baud rates such as 115200, 57600, 9600, and 1200 baud with 0% error. This eliminates framing errors that occur with approximate baud clocks derived from other frequencies, making the CB3LV-3I-18M4320 a standard choice for serial communication interface designs in embedded and networking equipment.
What logic output type does the CB3LV-3I-18M4320 provide, and what is its signal transition speed?
The CB3LV-3I-18M4320 provides an HCMOS/TTL compatible output with a maximum fall time of 8 ns. This fast edge speed ensures reliable operation with 3.3 V and 5 V logic families, and is compatible with FPGA and microcontroller clock inputs that require clean, fast-transitioning clock signals.
How can the enable/disable function of the CB3LV-3I-18M4320 benefit a battery-powered design?
The enable/disable pin allows a host microcontroller or power management IC to shut off the oscillator output when the UART interface is inactive, reducing dynamic power consumption. In a system operating on a 3.3 V supply, gating the 18.432 MHz clock can save several milliamps of current, extending battery life in portable industrial or IoT communication devices.
