101 / 126 page ![]() Chapter 9 DC and AC Operating Conditions ICS1893CF, Rev. F, 03/01/07 Mar. 2007 101 ICS1893CF Data Sheet Rev. F - Release Copyright © 2007, Integrated Device Technology, Inc. All rights reserved. 9.4 DC Operating Characteristics This section lists the ICS1893CF DC operating characteristics. 9.4.1 DC Operating Characteristics for Supply Current Table 9-4 lists the DC operating characteristics for the supply current to the ICS1893CF under various conditions. Note: All VDD_IO measurements are taken with respect to VSS (which equals 0 V). † These supply current parameters are measured through VDD pins to the ICS1893CF. The supply current parameters include external transformer currents. ‡ Measurements taken with 100% data transmission and the minimum inter-packet gap. 9.4.2 DC Operating Characteristics for TTL Inputs and Outputs Table 9-5 lists the 3.3-V DC operating characteristics of the ICS1893CF TTL inputs and outputs. Note: All VDD_IO measurements are taken with respect to VSS (which equals 0 V). Table 9-4. DC Operating Characteristics for Supply Current Parameter Operating Mode Symbol Min. Typ. Max. Units Supply Current† 100Base-TX‡ IDD_IO – – 11 mA IDD – – 125 mA Supply Current† 10Base-T‡ IDD_IO – – 8 mA IDD – – 160 mA Supply Current† Auto-Negotiation IDD_IO – – 8 mA IDD – – 90 mA Supply Current† Power-Down IDD_IO – – 5 mA IDD – – 5 mA Supply Current† Reset IDD – – 11 mA Table 9-5. 3.3-V DC Operating Characteristics for TTL Inputs and Outputs Parameter Symbol Conditions Min. Max. Units TTL Input High Voltage VIH VDD_IO = 3.47 V – 2.0 – V TTL Input Low Voltage VIL VDD_IO = 3.47 V – – 0.8 V TTL Output High Voltage VOH VDD_IO = 3.14 V IOH = –4 mA 2.4 – V TTL Output Low Voltage VOL VDD_IO = 3.14 V IOL = +4 mA – 0.4 V TTL Driving CMOS, Output High Voltage VOH VDD_IO = 3.14 V IOH = –4 mA 2.4 – V TTL Driving CMOS, Output Low Voltage VOL VDD_IO = 3.14 V IOL = +4 mA – 0.4 V |
