Figure 7.7 Receive Timing for Data Packet (with CRC-16)

The receivers connect directly to the USB cable. The block contains a separate differential receiver for HS and FS mode. Depending on the mode, the selected receiver provides the serial data stream through the mulitplexer to the RX Logic block. The FS mode section of the FS/HS RX block also consists of a single-ended receiver on each of the data lines to determine the correct FS LINESTATE. For HS mode support, the FS/HS RX block contains a squelch circuit to insure that noise is never interpreted as data.
