Technical details and manufacturing context for Baud Rate Generator / Clock Controller

Definition

The Baud Rate Generator / Clock Controller is a specialized electronic circuit within a Protocol Engine that produces accurate timing signals and baud rates required for serial data transmission and reception, ensuring synchronization between communicating devices. It typically uses a crystal oscillator or phase-locked loop (PLL) to generate a stable base frequency, which is then divided or multiplied to produce specific baud rates and clock signals for various communication protocols. This component is essential in systems where precise timing is critical, such as UART, SPI, I2C, and other serial interfaces. The device operates over an output frequency range of 1–200 MHz, covering standard baud rates up to 20 Mbps, with a frequency accuracy of ±0.01% at 25°C and nominal supply voltage. It requires a supply voltage of 1.8–3.3 V DC and draws a supply current of 1–10 mA at maximum frequency. The operating temperature range is -40 to 85°C, conforming to industrial grade standards IEC 60068-2-1 and IEC 60068-2-2. The output duty cycle is 45–55% at 50% load, and rise/fall times are 1–5 ns with a 15 pF load. The output drive capability is ±8 mA sink/source, and input logic levels are compatible with CMOS/TTL from 1.8V to 3.3V. The component is available in a QFN-16 package (4x4 mm) per JEDEC MO-220, and provides ESD protection of ±2 kV HBM per IEC 61000-4-2. Materials include silicon, copper, and ceramic substrate. For procurement, verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The Baud Rate Generator / Clock Controller generates precise timing signals by first creating a stable base frequency using a crystal oscillator or a phase-locked loop (PLL). This base frequency is then processed through frequency dividers or multipliers to produce the desired baud rates and clock signals for serial communication. The output frequency range is 1–200 MHz, with accuracy of ±0.01%. The device operates from a 1.8–3.3 V supply and consumes 1–10 mA. It provides a duty cycle of 45–55% and rise/fall times of 1–5 ns. The output can drive ±8 mA, and inputs accept CMOS/TTL levels. The operating temperature range is -40 to 85°C. The component is housed in a QFN-16 package and has ESD protection of ±2 kV.
