The HCLK frequency may be made to appear at the dedicated CLKOUT pin of the device. For low power operation, however, the CLKOUT pin can be disabled.
The peripherals operate at the HCLK rate, which may be selected to be equal to CCLK or CCLK 2, up to a maximum of a 75 MHz HCLK for the ADSP-21992BBC.
In order to attain the correct CCLK and HCLK values, the input clock frequency or crystal frequency depends on the internal operation of the clock generation PLL
The maximum junction temperature is limited to 140°C in order to meet all of the electrical specifications. It is ultimately the responsibility of the user to ensure that
