Joyce,

SN65HVD62 can work with a crystal at 4x 2.176 MHz frequency, while the crystal with +-30ppm is recommended. Please let me know if you have more questions.

Joyce,

The device was specified 45% to 55% duty cycle for external crystal. 40% to 60% may still work but it's not characterized. Please let me know if you have more questions.
