5 Pin Configuration and Functions

TUSB216RWB

12-Pin X2QFN

Top View

(1)

Pull-down and pull-up resistors for RX_SEN pin must follow RRXSEN1 and RRXSEN2 resistor recommendations in non I

2C mode.

(2)

Pull-up resistors for SDA and SCL pins in I2C mode should be RPull-up (depending on I2C bus voltage). If both SDA and SCL are pulled

up at power-up the device enters into I2C mode.

DESCRIPTION

NAME

NO.

BOOST

N/A

USB High-speed boost select via external pull down resistor.

Both edge boost and DC boost are controlled by a single pin in non-

I2C mode. In I2C mode edge boost and DC boost can be individually

controlled.

Sampled upon power up. Does not recognize real time adjustments.

Auto selects BOOST LEVEL = 3 when left floating.

CDP_ENZ

500 k

Ω PU

Set CDP_ENZ is low to enable BC 1.2 CDP controller

RX_SEN(1)/ENA_HS

I/O

N/A

In I2C mode:

Reserved for TI test purpose.

In non-I2C mode:

At reset: 3-level input signal RX_SEN. USB High-speed RX

Sensitivity Setting to Compensate ISI Jitter

H (pin is pulled high) – high RX sensitivity (high loss channel)

M (pin is left floating) – medium RX sensitivity (medium loss channel)

L (pin is pulled low) – low RX sensitivity (low loss channel)

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

High-speed mode. Asserted upon:

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].
