Notes:
1.
Use of the post-divider is required for frequencies lower than 20 MHz on CLK and CLK outputs. Use of the
post-divider is recommended for output frequencies lower than 65 MHz.
2.
Values for XTAL1 driven by an external clock
3.
Duty Cycle for Differential Output (CLK- CLK)
4.
Duty cycle measured at VOD/2 for Differential CLK Output
5.
Rise and fall time between 20% and 80% of VOD
6.
Duty cycle measured at 1.4V for TTL I/O
7.
Rise and fall time between 0.8 and 2.0 VDC for TTL I/O
8.
