SA5200D datasheet by Philips Semiconductors

SA5200D Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SA5200D?
  The recommended operating voltage range for the SA5200D is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I properly configure the clock input for the SA5200D?
  The clock input (CLKIN) should be a square wave with a frequency between 10 kHz and 100 kHz, and an amplitude of at least 2Vpp. A 10 kΩ resistor should be connected between the clock input and VCC.
• What is the purpose of the VREF pin on the SA5200D?
  The VREF pin is an internal voltage reference output that can be used as a reference voltage for external circuits. It is typically connected to a capacitor to ground to filter out noise.
• How do I calculate the output frequency of the SA5200D?
  The output frequency (fout) can be calculated using the formula: fout = (CLKIN / 2) * (R1 / R2), where R1 and R2 are the values of the external resistors connected to the R1 and R2 pins, respectively.
• What is the maximum output current of the SA5200D?
  The maximum output current of the SA5200D is 100 mA per output pin, with a total maximum current of 200 mA for both output pins combined.
