Freescale Semiconductor
Electrical Characteristics
Figure 2 shows the undershoot and overshoot voltages at the interfaces of this device.
Figure 2. Overshoot/Undershoot Voltage for GVDD/OVDD/LVDD/BVDD/TVDD
The core voltage must always be provided at nominal 1.1 V. Voltage to the processor interface I/Os are
provided through separate sets of supply pins and must be provided at the voltages shown in Table 2. The
input voltage threshold scales with respect to the associated I/O supply voltage. OVDD and LVDD based
receivers are simple CMOS I/O circuits and satisfy appropriate LVCMOS type specifications. The DDR
SDRAM interface uses a single-ended differential receiver referenced the externally supplied MVREF
signal (nominally set to GVDD/2) as is appropriate for the SSTL2 electrical signaling standard.
Junction temperature range

°C—
Notes:
1. This voltage is the input to the filter discussed in Section 21.2.1, “PLL Power Supply Filtering,” and not necessarily the voltage
at the AVDD pin, which may be reduced from VDD by the filter.
2. Caution: MVIN must not exceed GVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during
power-on reset and power-down sequences.
3. Caution: OVIN must not exceed OVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during
power-on reset and power-down sequences.
4. Caution: L/TVIN must not exceed L/TVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during
power-on reset and power-down sequences.

Notes:
2. Please note that with the PCI overshoot allowed (as specified above), the device
does not fully comply with the maximum AC ratings and device protection
guideline outlined in the PCI rev. 2.2 standard (section 4.2.2.3).
For I2C and JTAG, tCLOCK references SYSCLK.
For DDR, tCLOCK references MCLK.
For eTSEC, tCLOCK references EC_GTX_CLK125.
For LBIU, tCLOCK references LCLK.
For PCI, tCLOCK references PCIn_CLK or SYSCLK.
For SerDes, tCLOCK references SD_REF_CLK.
