-PFA,
- Attached patch provides further optimized 3630 & 3430 path for
calculating M2 stablization delay.
- The formula used to compute clkoutx2, is actually calculating for
clkoutm2x2 according to trm clkoutx2 = (Fref * 2 * M)/ (N + 1).
(Thanks to Eduardo for pointing this).
No, CLKOUTX2 is dependent on M2. Pls refer to table 3-45 (DPLL Operating Mode and Latency) in 3630 TRM Version D.
Yes! Stabilization delay for CLKOUTx2 is dependent on M2.
Confusion prevailed because of the section 3.5.3.3.3.1 where clkoutx2 is
not dependent on M2 factor. And moreover the formula used to calculate
clkoutx2 in this case looks like the one used for computing clkout_M2X2 :)
Thanks,
Ambresh
