3 Description
The TUSB215 is a USB High-Speed (HS) signal
conditioner, designed to compensate for ISI signal
loss in a transmission channel which helps passing
USB electrical compliance tests.
TUSB215 has a patent-pending design which is
agnostic to USB Low Speed (LS) and Full Speed
(FS) signals. LS and FS signal characteristics are
unaffected by the TUSB215 while HS signals are
compensated.
Programmable signal AC boost and DC boost permits
fine tuning device performance to optimize High
Speed signals at the connector, this allows use in
many different applications.
In addition, TUSB215 is compatible with the USB On-
The-Go (OTG) and Battery Charging (BC) protocols.
TUSB215 further acts as Charging Downstream Port
(CDP) controller and handles the necessary
handshakes with the downstream device.

RSTN asserted: 500 kPD
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.
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:
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].
USB High Speed positive port.
USB High Speed negative port.
Ground
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:
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.
