DS1339C-33# datasheet by Maxim Integrated Products

DS1339C-33# Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DS1339C-33#?
  The recommended power-up sequence is to apply VCC first, followed by a valid clock signal, and then the RST pin can be released.
• How do I ensure that the DS1339C-33# oscillator starts reliably?
  To ensure reliable oscillator start-up, a 1-10 kΩ resistor can be connected between the X1 pin and ground, and a 10-22 pF capacitor can be connected between the X2 pin and ground.
• What is the maximum frequency deviation of the DS1339C-33# oscillator?
  The maximum frequency deviation of the DS1339C-33# oscillator is ±100 ppm over the entire operating temperature range.
• Can I use the DS1339C-33# in a battery-powered application?
  Yes, the DS1339C-33# is suitable for battery-powered applications due to its low power consumption (typically 1.5 μA at 3 V) and ability to operate from a single lithium cell or two alkaline cells.
• How do I interface the DS1339C-33# with a microcontroller?
  The DS1339C-33# can be interfaced with a microcontroller using a 3-wire serial interface (SCLK, SDATA, and RST) or a 2-wire I²C interface (SCL and SDA).
