Receive Data. CMOS level output for USB differential input.
Output Enable. Active LOW, enables the transceiver to transmit data on the bus.
When not active, the transceiver is in receive mode.
Mode. When left unconnected, a weak pull-up transistor pulls it to V
GND, the V
Inputs to differential driver. (Outputs from SIE.)
Buffered version of D- and D+. Outputs are logic “0” and logic “1.” Used to detect
single ended zero (/SEO), error conditions, and interconnected speed. (Input to SIE).
Data+, Data-. Differential data bus conforming to the Universal Serial Bus standard.
Suspend. Enables a low-power state while the USB bus is inactive. While the
suspend pin is active, it drives the RCV pin to a logic “0” state. Both D+ and D- are 3-
STATE.
Edge Rate Control. Logic “1” operates at edge rates for “full speed.” Logic “0”
operates edge rates for “low speed.”
3.0 to 3.6 power supply.
Ground reference.
