Programmable Output Clock (CLKOUT) Rise and Fall Times
The output clock rise and fall times (tr/tf) of each clock output can be programmed independently to match drive level
to load impedance.
Notes:
1. All typical values are at respective nominal VDD values.
2. The worst case rise and fall times variations are +/- 20% for C-Grade and +/-30% for I-grade.
