PARAMETER
Measure V(VCCL) - V(EAOUT),
Relative to Error Amplifier maximum
voltage.
Measure PHSOUT pulse numbers from
V(EAOUT) = V(VCCL) to PGOOD =
low.

Compare to V(VDAC)
Compare to V(VDAC)
Measure time from V(VO) > V(VDAC)
(250mV overdrive) to V(IIN) transition to
> 0.9 * V(VCCL).
Measure time from V(VO) > V(VDAC)
(250mV overdrive) to V(ROSC/OVP)
transition to >1V.
Measure V(VCCL)-V(ROSC/OVP)
V(VCCLDRV)=1.8V. Measure V(VCCL)-
V(ROSC/OVP)
