111 / 148 page  Intel® IXP45X and Intel® IXP46X Product Line of Network Processors August 2006 Datasheet Document Number: 306261-004US 111 Datasheet—Intel® IXP45X and Intel® IXP46X Product Line of Network Processors 5.5.9 High-Speed, Serial Interface 0 DC Parameters 5.5.10 High-Speed, Serial Interface 1 DC Parameters VOHDRV2 Output-high voltage IOUT = -20 mA 2.4 V 1, 4 VOLDRV2 Output-low voltage IOUT = 20 mA 0.4 V 1, 4 IIL Input-leakage current 0 < VIN < VCCP -10 10 µA CIN Input-pin capacitance 5 pF 2 Table 38. High-Speed, Serial Interface 0 DC Parameters Symbol Parameter Conditions Min. Typ. Max. Units Notes VIH Input-high voltage 2.0 V VIL Input-low voltage 0.8 V VOH Output-high voltage IOUT = - 6mA 2.4 V VOL Output-low voltage IOUT = 6mA 0.4 V IIL Input-leakage current 0 < VIN < VCCP -10 10 µA CIN Input-pin capacitance 5 pF 1 Notes: 1. These values are typical values seen by the manufacturing process and are not tested. Table 39. High-Speed, Serial Interface 1 DC Parameters Symbol Parameter Conditions Min. Typ. Max. Units Notes VIH Input-high voltage 2.0 V VIL Input-low voltage 0.8 V VOH Output-high voltage IOUT = -6mA 2.4 V VOL Output-low voltage IOUT = 6mA 0.4 V IIL Input-leakage current 0 < VIN < VCCP -10 10 µA CIN Input-pin capacitance 5 pF 1 Notes: 1. These values are typical values seen by the manufacturing process and are not tested. Table 37. Expansion Bus DC Parameters (Sheet 2 of 2) Symbol Parameter Conditions Min. Typ. Max. Units Notes Notes: 1. These values are typical values seen by the manufacturing process and are not tested. 2. The values represented with this voltage parameter would typically be used in a system in which the expansion bus interfaces a single load of 6pF placed less than 2 inches away from the IXP45X/IXP46X network processors. This drive strength setting should be used to avoid ringing when minimal loading is attached. Please use IBIS models and simulation tools to guarantee the design. 3. The values represented with this voltage parameter would typically be used in a system in which the expansion bus interfaces four loads of 6pF each. All components are placed no further than 4 inches away from the IXP45X/IXP46X network processors. This drive strength setting should be used to avoid ringing when medium loading is attached. Please use IBIS models and simulation tools to guarantee the design. 4. The values represented with this voltage parameter would typically be used in a system in which the expansion bus interfaces eight loads of 6pF and all components are placed less than 6 inches from the IXP45X/IXP46X network processors. Another use case of this drive strength would typically be four loads of 6pF operating at 80MHz. This drive strength setting should be used to avoid ringing when maximum loading or frequency is utilized. Please use IBIS models and simulation tools to guarantee the design. |
