Notes:

1.VTT_PWRGD can be designed to be driving directly the OUTEN input.

2.Tb and Td voltage slopes are determined by soft start logic of the PWM controller.

3.Vboot is a default power-on Vcc (Core) value. Upon detection of a valid Vtt supply, the PWM controller is to regulate to this value until the VID codes are read. The Vboot voltage is 1.1 V

4.VTT is the processor termination regulator’s output voltage and the VTT_PWRGD is the VTT regulator’s power good status indicator.

5.Unless otherwise noted, all specifications in this table apply to all processor frequencies.

6.This specification requires that the VID signals be sampled no earlier than 10 µs after VCC (at VCC_BOOT voltage) and VTT are stable.

7.Parameter must be measured after applicable voltage level is stable. “Stable” means that the power supply is in regulation as defined by the minimum and maximum DC/AC specifications for all components being powered by it.

8.The maximum PWRGOOD rise time specification denotes the slowest allowable rise time for the processor. Measured between (0.3 * VTT) and (0.7 * VTT).
