RESET Initialization
This section describes the DC and AC electrical specifications for the reset initialization timing and
electrical requirements of the chip.
5.1
RESET DC Electrical Characteristics
This table provides the DC electrical characteristics for the RESET pins of the device.

Notes:
1. Rise and fall times for EC_GTX_CLK125 are measured from 0.5 and 2.0 V for LVDD = 2.5 V and from 0.6 and 2.7 V for
LVDD =3.3 V.
2. EC_GTX_CLK125 is used to generate the GTX clock for the eTSEC transmitter with 2% degradation. The
EC_GTX_CLK125 duty cycle can be loosened from 47%/ 53% as long as the PHY device can tolerate the duty cycle
generated by the eTSEC GTX_CLK. See Section 8.2.2, “RGMII and RTBI AC Timing Specifications,” for the duty cycle for
10Base-T and 100Base-T reference clock.

Notes:
This table applies for pins PORESET and HRESET. The PORESET is input pin, thus stated output voltages are not relevant.
HRESET and SRESET are open drain pin, thus VOH is not relevant for these pins.
