8 / 28 page  Philips Semiconductors Product specification PDIUSBH11A Universal Serial Bus Hub 1999 Jul 22 8 Pin description (MODE 1 – Individual Overcurrent) PIN NO PIN SYMBOL TYPE DRIVE DESCRIPTION 1 TEST1 Input Connect to VCC for 48MHz crystal input. Connect to Ground for 12MHz crystal input. 2 TEST2 Input Connect to VCC 3 TEST3 Input Connect to Ground 4 RESET_N Input ST Power-on reset 5 GND Power Ground reference 6 XTAL1 Input Crystal connection 1 (48 or 12MHz depending on TEST1 pin) 7 XTAL2 Output Crystal connection 2 (48 or 12MHz depending on TEST1 pin) 8 CLKOUT Output 3mA Programmable output clock for external devices 9 VCC Power Voltage supply 3.3V ± 0.3V 10 OCURRENT2_N Input ST Downstream port 2 overcurrent notice. This pin is also used to sense the USB VBUS. A LOW on this pin of less than 2 seconds is interpreted as an overcurrent notice; longer than 2 seconds is interpreted as loss of VBUS. 11 SWITCH_N Output OD6 Enables power to downstream ports 12 SUSPEND Output OD6 Device is in suspended state 13 DN2_GL_N Output OD6 Downstream port 2 GoodLink ™ LED indicator 14 OCURRENT3_N Input ST Downstream port 3 over-current notice 15 OCURRENT4_N Input ST Downstream port 4 over-current notice 16 OCURRENT5_N Input ST Downstream port 5 over-current notice 17 INT_N Output OD6 Connect to microcontroller interrupt 18 SDA I/O OD6 I2C bi-directional data 19 SCL I/O OD6 I2C bit-clock 20 GND Power Ground reference 21 DN5_DP AI/O Downstream port 5 D+ connection 22 DN5_DM AI/O Downstream port 5 D– connection 23 DN4_DP AI/O Downstream port 4 D+ connection 24 DN4_DM AI/O Downstream port 4 D- connection 25 DN3_DP AI/O Downstream port 3 D+ connection 26 DN3_DM AI/O Downstream port 3 D- connection 27 DN2_DP AI/O Downstream port 2 D+ connection 28 DN2_DM AI/O Downstream port 2 D- connection 29 AGND Power Analog Ground reference 30 AVCC Power Analog voltage supply 3.3V ± 0.3V 31 UP_DP AI/O Upstream D+ connection 32 UP_DM AI/O Upstream D- connection NOTES: 1. Signals ending in _N indicate active low signals. ST: Schmitt Trigger OD6: Open Drain with 6 mA drive AI/O: Analog I/O |
