Notes:
1. Controlled by design and process and not directly tested. Verified on initial part evaluation.
2. Each part is tested at 85 deg C for the given specification.
3. The chip may not operate properly at clock frequencies below MIN and MAX.
4. Capacitive output load is 20pf. Delays are measured from the rising edge of the clock to the output level rising
above or falling below 1.3v.
5. t_CSPW must be at least five clock cycles wide if the SYNC_COEF control bit is set (See Section 6.3).
6. Capacitive output load is 80pf.
7. Current changes linearly with voltage and clock speed.
