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.
Anytime an upstream device gets reconnected the redriver automatically senses the connection and goes to
normal operating mode. This operation requires no setting to the device.
