45 / 67 page ![]() PPC405EX – PowerPC 405EX Embedded Processor Revision 1.09 - August 21, 2007 AMCC Proprietary 45 Preliminary Data Sheet Ratings and Specifications Table 7. Absolute Maximum Ratings The absolute maximum ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause permanent damage to the device. None of the performance specification contained in this document are guaranteed when operating at these maximum ratings. Characteristic Symbol Value Unit Notes Supply Voltage (Internal Logic) VDD 0 to +1.6 V Core SerDes Analog Supply Voltage AVDD 0 to +1.6 V 1 PLL SerDes Analog Supply Voltage AHVDD 0 to +2.6 V 1 I/O Supply Voltage OVDD 0 to +3.6 V SDRAM DDR1(2) Supply Voltage SVDD 0 to +2.6 (+1.9) V CMOS Supply Voltage EOVDD 0 to +2.6 V System PLL Analog Supply Voltage SAVDD 0 to +2.6 V 1 Ethernet PLL Analog Supply Voltage EAVDD 0 to +2.6 V 1 Input Voltage (3.3V LVTTL receivers) VIN 0 to +3.6 V Storage Temperature Range TSTG −55 to +150 °C Case Temperature Range under bias TC −40 to +120 °C Junction Temperature Range TJMax −40 to +125 °C 1. The analog voltages can be derived from the +1.2V and +2.5V supplies, but must be filtered as shown below before entering the PPC405EX. Use a separate filter for each voltage. This circuit can be used for AVDD, AHVDD , SAVDD, and EAVDD. Use AGND with AVDD and AHVDD. Use SAGND with SAVDD. Use EAGND with EAVDD. These analog grounds must be brought out and connected to the digital ground plane at the filter capacitor. Keep all wire lengths as short as possible. VDD C1 AVDD L1 L1 – Murata BLM18AG121SN1D C1 – 0.1 μF ceramic AGND GND |
