DESCRIPTION

NAME

NO.

USB High Speed AC boost select via external pull down resistor.

Sampled upon de-assertion of RSTN. Does not recognize real time

adjustments.

See application section for details. Auto selects maximum AC boost level

when left floating.

N/A

2, 3

N/A

Leave unconnected.

In I2C mode:

Reserved for TI test purpose.

In non-I2C mode:

At reset: 3-level input signal DC_BOOST. USB High Speed DC signal boost

selection.

H (pin is pulled high) – 80 mV

M (pin is left floating) – 60 mV

L (pin is pulled low) – 40 mV

After reset: Output signal ENA_HS. Flag indicating that channel is in High

Speed mode. Asserted upon:

DC_BOOST⁽¹

⁾/ENA_HS

I/O

1. Detection of USB-IF High Speed test fixture from an unconnected state

followed by transmission of USB TEST_PACKET pattern.

2. Squelch detection following USB reset with a successful HS handshake [HS

handshake is declared to be successful after single chirp J chirp K pair where

each chirp is within 18 μs – 128 μs].

I/O

N/A

USB High Speed positive port.

USB High Speed negative port.

Ground

PWR

1.8-V LDO output. Only enabled when operating in High Speed mode.

Requires 0.1-µF external capacitor to GND to stabilize the core.

USB High Speed negative port..

USB High Speed positive port.

I2C Mode:

Bidirectional I2C data pin [I2C address = 0x2C].

In non I2C mode:

SDA⁽²⁾

I/O

RSTN asserted: 500 kΩ PD

Reserved for TI test purpose.

(1) Pull-down and pull-up (to 3.3 V) resistors for DC_BOOST pins must be between 22 kΩ to 47 kΩ in non I²C mode.

(2) Pull-up resistors for SDA and SCL pins in I²C mode should be 4.7 kΩ (5%). If both SDA and SCL are pulled up at reset the device

enters into I²C mode.
