Notes:
1. Rise and fall times for EC_GTX_CLK125 are measured from 0.5V and 2.0V for L/TVDD=2.5V, and from 0.6 and 2.7V for
L/TVDD=3.3V at 0.6 V and 2.7 V.
2. EC_GTX_CLK125 is used to generate the GTX clock for the eTSEC transmitter with 2% degradation. 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 2.9.2.6, “RGMII and RTBI AC Timing Specifications,” for duty cycle for 10Base-T and 100Base-T
reference clock.

Notes:
1. Caution: The DDR complex clock to DDRCLK ratio settings must be chosen such that the resulting DDR complex
clock frequency does not exceed the maximum or minimum operating frequencies. See Section 2.23.4,
“DDR/DDRCLK PLL Ratio,” for ratio settings.
2. Rise and fall times for DDRCLK are measured at 0.6 V and 2.7 V.
3. The DDRCLK driver’s closed loop jitter bandwidth should be <500 kHz at –20 dB. The bandwidth must be set low to
allow cascade-connected PLL-based devices to track DDRCLK drivers with the specified jitter.
4. For spread spectrum clocking, guidelines are +0% to –1% down spread at a modulation rate between 20 kHz and
60 kHz on DDRCLK.
