TYPE⁽¹⁾

DESCRIPTION

NAME

NO.

CRX1p

Differential positive input for USB port 1. Should be connected to SSRXp pin of USB

connector. Connection can be DC-coupled to USB connector. Optionally, connection can

be through an external 330 nF AC-coupling capacitor.

No internal connection.

CTX1n

Differential negative output for USB port 1. Should be connected to SSTXn pin of USB

connector through an external 220 nF AC-coupling capacitor.

CTX1p

Differential positive output for USB port 1. Should be connected to SSTXp pin of USB

connector through an external 220 nF AC-coupling capacitor.

In I²C mode, this pin along with A1 pin selects the 7-bit I2C target address (refer to 表7-7).

In pin-strap mode, this pin along with SSEQ1 selects the receiver EQ for SSTX1 and/or

SSTX2 (refer to 表7-3).

SSEQ0/A0

4-level I

(PU/PD)

CRX2n

CRX2p

Differential negative input for USB port 2. Should be connected to SSRXn pin of USB

connector. Connection can be DC-coupled to USB connector. Optionally, connection can

be through an external 330 nF AC-coupling capacitor.

Differential positive input for USB port 2. Should be connected to SSRXp pin of USB

connector. Connection can be DC-coupled to USB connector. Optionally, connection can

be through an external 330 nF AC-coupling capacitor.

CEQ0

In pin-strap mode, this pin along with CEQ1 selects the receiver EQ for CRX1 and/or

CRX2 (Refer to 表7-2).

4-level I

(PU/PD)

CTX2n

Differential negative output for USB port 2. Should be connected to SSTXn pin of USB

connector through an external 220 nF AC-coupling capacitor.

CTX2p

Differential positive output for USB port 2. Should be connected to SSTXp pin of USB

connector through an external 220 nF AC-coupling capacitor.

Thermal Pad

Thermal pad. Connect to a solid ground plane.

(1) I = Input, O = Output, I/O = Input or Output, G = Ground, P = Power, PD = Internal Pull-down, PU = Internal Pull-up.
