DESCRIPTION

The SN65LVPE502 is a dual channel, single lane USB 3.0 redriver and signal conditioner supporting data rates

of 5.0Gbps. The device complies with USB 3.0 spec revision 1.0, supporting electrical idle condition and low

frequency periodic signals (LFPS) for USB 3.0 power management modes.

Programmable EQ, De-Emphasis and Amplitude Swing

The SN65LVPE502 is designed to minimize signal degradation effects such as crosstalk and inter-symbol

interference (ISI) that limits the interconnect distance between two devices. The input stage of each channel

offers selectable equalization settings that can be programmed to match loss in the channel. The differential

outputs provide selectable de-emphasis to compensate for the anticipated distortion USB 3.0 signal will

experience. Level of de-emphasis will depend on the length of interconnect and its characteristics. The

SN65LVPE502 provides a unique way to tailor output de-emphasis on a per channel basis with use of DE and

OS pins. All Rx and Tx equalization settings supported by the device are programmed by six 3-state pins as

shown in Table 2.

Low Power Modes

The device supports three low power modes as described below.

1. Sleep Mode

Initiated anytime EN_RXD undergoes a high to low transition or when device powers up with EN_RXD set

low. In sleep mode both input and output terminations are held at HiZ and device ceases operation to

conserve power. Sleep mode max power consumption is 1mW, entry time is 2µs, device exits sleep mode to

Rx.Detect mode after EN_RXD is driven to V_CC, exit time is 100µs max.

2. RX Detect Mode – When no remote device is connected

Anytime SN65LVPE502 detects a break in link (i.e., when upstream device is disconnected) or after powerup

fails to find a remote device, SN65LVPE502 goes to Rx Detect mode and conserves power by shutting down

majority of the internal circuitry. In this mode, input termination for both channels are driven to Hi-Z. In Rx

Detect mode device power is <10mW(TYP) or less than 5% of its normal operating power This feature is

useful in saving system power in mobile applications like notebook PC where battery life is critical.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
