Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 6.2 High-speed Signaling Eye Patterns High-speed USB signals are characterized using eye patterns. For measuring the eye patterns 4 points have been defined (see Figure 6.3). The Universal Serial Bus Specification Rev.2.0 defines the eye patterns in several ‘templates’. The two templates that are relevant to the PHY are shown below.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet The eye pattern in Figure 6.4 defines the transmit waveform requirements for a hub (measured at TP2 of Figure 6.3) or a device without a captive cable (measured at TP3 of Figure 6.3). The corresponding signal levels and timings are given in table below. Time is specified as a percentage of the unit interval (UI), which represents the nominal bit duration for a 480 Mbit/s transmission rate.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet The eye pattern in Figure 6.5 defines the receiver sensitivity requirements for a hub (signal applied at test point TP2 of Figure 6.3) or a device without a captive cable (signal applied at test point TP3 of Figure 6.3). The corresponding signal levels and timings are given in the table below. Timings are given as a percentage of the unit interval (UI), which represents the nominal bit duration for a 480 Mbit/s transmission rate.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet Chapter 7 Functional Overview Figure 2.1 on page 7 shows the functional block diagram of the USB3290. Each of the functions is described in detail below. 7.1 Modes of Operation The USB3290 supports an 8-bit bi-directional parallel interface. 7.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet Figure 7.2 shows the relationship between CLKOUT and the receive data control signals in FS mode. RXACTIVE "frames" a packet, transitioning only at the beginning and end of a packet. However transitions of RXVALID may take place any time 8 bits of data are available. Figure 7.1 also shows how RXVALID is only asserted for one CLKOUT cycle per byte time even though the data may be presented for the full byte time.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet The behavior of the Transmit State Machine is described below. 7.5 Asserting a RESET forces the transmit state machine into the Reset state which negates TXREADY. When RESET is negated the transmit state machine will enter a wait state. The SIE asserts TXVALID to begin a transmission. After the SIE asserts TXVALID it can assume that the transmission has started when it detects TXREADY has been asserted.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet When the EOP is detected the state machine will enter the Strip EOP state and negate RXACTIVE and RXVALID. After the EOP has been stripped the Receive State Machine will reenter the RX Wait state and begin looking for the next packet. The behavior of the Receive State Machine is described below: RXACTIVE and RXREADY are sampled on the rising edge of CLKOUT. In the RX Wait state the receiver is always looking for SYNC.

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 receivers connect directly to the USB cable. This block contains a separate differential receiver for HS and FS mode.

This block requires an external 12kΩ, 1% tolerance, external reference resistor connected from RBIAS to ground. 7.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet Chapter 8 Application Notes The following sections consist of select functional explanations to aid in implementing the USB3290 into a system. For complete description and specifications consult the USB 2.0 Transceiver Macrocell Interface Specification and Universal Serial Bus Specification Revision 2.0. 8.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 8.2 OPMODES The OPMODE[1:0] pins allow control of the operating modes. Table 8.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 8.4 SE0 Handling For FS operation, IDLE is a J state on the bus. SE0 is used as part of the EOP or to indicate reset. When asserted in an EOP, SE0 is never asserted for more than 2 bit times. The assertion of SE0 for more than 2.5us is interpreted as a reset by the device operating in FS mode. For HS operation, IDLE is a SE0 state on the bus. SE0 is also used to reset a HS device. A HS device cannot use the 2.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 8.6 Suspend Detection If a HS device detects SE0 asserted on the bus for more than 3ms (T1), it reverts to FS mode. This enables the FS pull-up on the DP line in an attempt to assert a continuous FS J state on the bus. The SIE must then check LINESTATE for the J condition. If J is asserted at time T2, then the upstream port is asserting a soft SE0 and the USB is in a J state indicating a suspend condition.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 8.7 HS Detection Handshake The High Speed Detection Handshake process is entered from one of three states: suspend, active FS or active HS. The downstream facing port asserting an SE0 state on the bus initiates the HS Detection Handshake. Depending on the initial state, an SE0 condition can be asserted from 0 to 4 ms before initiating the HS Detection Handshake. These states are described in the USB 2.0 specification.

Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 8.9 HS Detection Handshake – HS Downstream Facing Port Upon entering the HS Detection process (T0) XCVRSELECT and TERMSELECT are in FS mode. The DP pull-up is asserted and the HS terminations are disabled. The SIE then sets OPMODE to Disable Bit Stuffing and NRZI encoding, XCVRSELECT to HS mode, and begins the transmission of all 0's data, which asserts a HS K (chirp) on the bus (T1). The device chirp must last at least 1.

DP pull-up enabled, HS terminations disabled. 0 (reference) T1 Device asserts Chirp K on the bus. T0 < T1 < HS Reset T0 + 6.0ms T2 Device removes Chirp K from the bus. 1 ms minimum width. T0 + 1.0ms < T2 < HS Reset T0 + 7.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet Notes: 8.10 T0 may be up to 4ms after HS Reset T0. The SIE must use LINESTATE to detect the downstream port chirp sequence. Due to the assertion of the HS termination on the host port and FS termination on the device port, between T1 and T7 the signaling levels on the bus are higher than HS signaling levels and are less than FS signaling levels.

Table 8.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 8.11 Assertion of Resume In this case, an event internal to the device initiates the resume process. A device with remote wakeup capability must wait for at least 5ms after the bus is in the idle state before sending the remote wake-up resume signaling. This allows the hubs to get into their suspend state and prepare for propagating resume signaling.
Small Footprint Hi-Speed USB 2.0 Device PHY with UTMI Interface Datasheet 8.12 Detection of Resume Resume signaling always takes place in FS mode (TERMSELECT and XCVRSELECT = FS enabled), so the behavior for a HS device is identical to that of a FS device. The SIE uses the LINESTATE signals to determine when the USB transitions from the 'J' to the 'K' state and finally to the terminating FS EOP (SE0 for 1.25us-1.5µs.). The resume signaling (FS 'K') will be asserted for at least 20ms.
