70 / 76 page ![]() BCM5222 Preliminary Data Sheet 7/20/04 Broadcom Corporation Page 58 Electrical Characteristics Document 5222-DS02-405-R Section 7: Electrical Characteristics Table 47 provides the absolute maximum ratings for the BCM5222. The recommended operating conditions for the BCM5222 are shown in Table 48. Table 49 provides the package thermal characteristics. Table51onpage59 gives the electrical characteristics of the BCM5222. Table 47: Absolute Maximum Ratings Symbols Parameter Pin Min Max Unit VDD Supply Voltage OVDD, BIASVDD GND - 0.3 3.465 V DVDD, AVDD, PLLAVDD GND - 0.3 1.89 V VI Input Voltage GND - 0.3 OVDD + 0.3 V II Input Current ±10 mA Note: These specifications indicate levels where permanent damage to the device may occur. Functional operation is not guaranteed under these conditions. Operation at absolute maximum conditions for extended periods may adversely affect long-term reliability of the device.
