542MLFT - Renesas Electronics

Description: The 542 is cost effective way to produce a high-quality clock output divided from a clock input. The chip accepts a clock input up to 156 MHz at 3.3 V and produces a divide by 2, 4, 6, 8, 12, or 16 of the input clock. There are two outputs on the chip, one being a low-skew divide by two of the other. For instance, if an 100 MHz input clock is used, the 542 can produce low-skew 50 MHz and 25 MHz clocks, or low skew 25 MHz and 12.5 MHz clocks. The chip has an all-chip power-down mode that stops the outputs lo

542MLFT Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 542MLFT is -40°C to 125°C.
  • To configure the 542MLFT for low-power mode, set the PWRDN pin high and ensure that the VCC pin is within the recommended voltage range. Additionally, disable any unused peripherals and adjust the clock frequency to minimize power consumption.
  • The maximum clock frequency supported by the 542MLFT is 200 MHz.
  • To implement a watchdog timer on the 542MLFT, use the built-in watchdog timer module. Configure the WDTCSR register to set the timeout period and enable the watchdog timer. The watchdog timer will reset the device if it is not reset within the specified timeout period.
  • Yes, the 542MLFT can be used with an external crystal oscillator. Connect the crystal oscillator to the XTAL1 and XTAL2 pins, and configure the clock source to use the external oscillator.
