6. System Integration
6.1 Clocking System
The clocking system generates, divides, and distributes clocks
throughout the PSoC system. For the majority of systems, no
external crystal is required. The IMO and PLL together can
generate up to a 66 MHz clock, accurate to ±1 percent over
voltage and temperature. Additional internal and external clock
sources allow each design to optimize accuracy, power, and
cost. All of the system clock sources can be used to generate
other clock frequencies in the 16-bit clock dividers and UDBs for
anything the user wants, for example a UART baud rate
generator.
Clock generation and distribution is automatically configured
through the PSoC Creator IDE graphical interface. This is based
on the complete system’s requirements. It greatly speeds the
design process. PSoC Creator allows you to build clocking
systems with minimal input. You can specify desired clock
frequencies and accuracies, and the software locates or builds a
clock that meets the required specifications. This is possible
because of the programmability inherent PSoC.
Key features of the clocking system include:
