11.2.1 Design Requirements

The TUSB2E11 requires a valid reset signal as described in the Power Supply Recommendations section.

For design examples, use the parameters shown in Table 11-1, Table 11-2, and Table 11-3.

Table 11-1 Design Parameters for High Loss USB 2.0 System Using I2C
PARAMETER VALUE(1)
VDD3V3 3.3V ±10%
VDD1V8 1.8V ±5%
I2C support required in system (Yes or No) Yes
Parameter Register Setting Value
USB 2.0 TX Swing (peak to peak) U_TX_ADJUST_PORT1
(Offset = 70h)		 7Ch 980mVp-p
USB 2.0 TX Pre-emphasis U_HS_TX_PRE_EMPHASIS_P1
(Offset = 71h)		 3Ch 2.1dB
USB 2.0 RX Equalization U_RX_ADJUST_PORT1
(Offset = 72h)		 92h 1.09dB
USB 2.0 HS host disconnect threshold (peak differential) U_DISCONNECT_SQUELCH_PORT1
(Offset = 73h)		 83h 685mV
USB 2.0 HS squelch/RX sensitivity threshold (peak differential) U_DISCONNECT_SQUELCH_PORT1
(Offset = 73h)		 83h 111mV
Table 11-2 Design Parameters for Medium Loss USB 2.0 System Using I2C
PARAMETER VALUE(1)
VDD3V3 3.3V ±10%
VDD1V8 1.8V ±5%
I2C support required in system (Yes or No) Yes
Parameter Register Setting Value
USB 2.0 TX Swing (peak to peak) U_TX_ADJUST_PORT1
(Offset = 70h)		 79h 920mVp-p
USB 2.0 TX Pre-emphasis U_HS_TX_PRE_EMPHASIS_P1
(Offset = 71h)		 39h 0.9dB
USB 2.0 RX Equalization U_RX_ADJUST_PORT1
(Offset = 72h)		 92h 1.09dB
USB 2.0 HS host disconnect threshold (peak differential) U_DISCONNECT_SQUELCH_PORT1
(Offset = 73h)		 83h 685mV
USB 2.0 HS squelch/RX sensitivity threshold (peak differential) U_DISCONNECT_SQUELCH_PORT1
(Offset = 73h)		 83h 111mV
(1) These parameters are starting values for a high loss system. Further tuning might be required based on specific loss profile and measurements.
