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 VCC, 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 200kΩ pull-up/pull-down. When pins are left as NC board leakage at this pin pad must be < 1 µA otherwise drive to VCC/2 to assert mid-level state. Table 2.
