11 / 33 page  TUSB8040 www.ti.com SLLSE42F – SEPTEMBER 2010 – REVISED OCTOBER 2011 2.3 USB Downstream Signals Table 2-3. USB Downstream Signals PIN NO. SIGNAL NAME TYPE DESCRIPTION PFP RKM USB_SSTXP_DN0 O 8 B4 USB SuperSpeed transmitter differential pair (positive) USB_SSTXM_DN0 O 9 A4 USB SuperSpeed transmitter differential pair (negative) USB_SSRXP_DN0 I 6 B3 USB SuperSpeed receiver differential pair (positive) USB_SSRXM_DN0 I 7 A3 USB SuperSpeed receiver differential pair (negative) USB_DP_DN0 I/O 2 B1 USB high-speed differential transceiver (positive) USB_DM_DN0 I/O 3 A1 USB high-speed differential transceiver (negative) USB port power on control for downstream power/battery charging enable. The terminal is used for control of the downstream power switch; in addition, the value of the terminal is sampled at the de-assertion of reset to determine the value of the battery charger support for the port as indicated in the Battery Charger Support register: PWRON0z_BATEN0 I/O, PD 39 B19 0 = Battery charging not supported 1 = Battery charging supported The TUSB8040PFP only supports ganged mode. This terminal provides the port power control for all downstream ports. This terminal also determines the battery charging support of all downstream ports. USB downstream port over-current detection. The TUSB8040PFP only supports ganged mode. This terminal receives the over-current indication for all downstream ports. 0 = An overcurrent event has occurred OVERCUR0z I, PU 40 B21 1 = An overcurrent event has not occurred This terminal should be pulled high using a 10-k Ω resistor if power management is not implemented. If power management is enabled, the external circuitry needed should be determined by the power management device. USB_SSTXP_DN1 O 55 B34 USB SuperSpeed transmitter differential pair (positive) USB_SSTXM_DN1 O 56 A37 USB SuperSpeed transmitter differential pair (negative) USB_SSRXP_DN1 I 53 B33 USB SuperSpeed receiver differential pair (positive) USB_SSRXM_DN1 I 54 A36 USB SuperSpeed receiver differential pair (negative) USB_DP_DN1 I/O 60 B36 USB High-speed differential transceiver (positive) USB_DM_DN1 I/O 59 A39 USB High-speed differential transceiver (negative) USB Port 1 Power On Control for Downstream Power/Battery Charging Enable. The terminal is used for control of the downstream power switch for Port 1. In addition, the value of the terminal is sampled at the de-assertion of reset to determine the value of the battery charger support for Port 1 as indicated in the Battery Charger PWRON1z_BATEN1 I/O, PD A21 Support register: 0 = Battery Charging Not Supported 1 = Battery Charging Supported USB Port 1 Over-Current Detection. 0 = An overcurrent event has occurred 1 = An overcurrent event has not occurred OVERCUR1z I, PU A23 This terminal should be pulled high using a 10K resistor if power management is not implemented. If power management is enabled, the external circuitry needed should be determined by the power switch. USB_SSTXP_DN2 O 14 B7 USB SuperSpeed transmitter differential pair (positive) USB_SSTXM_DN2 O 15 A8 USB SuperSpeed transmitter differential pair (negative) USB_SSRXP_DN2 I 12 B6 USB SuperSpeed receiver differential pair (positive) USB_SSRXM_DN2 I 13 A7 USB SuperSpeed receiver differential pair (negative) USB_DP_DN2 I/O 17 A9 USB High-speed differential transceiver (positive) USB_DM_DN2 I/O 18 B9 USB High-speed differential transceiver (negative) Copyright © 2010–2011, Texas Instruments Incorporated PIN DESCRIPTIONS 11 Submit Documentation Feedback Product Folder Link(s): TUSB8040 |
