The TX2 provides a high-speed physical layer interface that operates at the maximum allowable USB 2.0 bandwidth. This allows the system designer to keep the complex high-speed analog USB components external to the digital ASIC which decreases development time and associated risk. A standard interface is provided that is USB 2.0-certified and is compliant with Transceiver Macrocell Interface (UTMI) specification version 1.05 dated 3/29/01. Two packages are defined for the family: 56-pin SSOP and 48-pin FBGA. The function block diagram is shown in Figure 1-1.

TX2 does not support the low-speed (LS) signaling rate of 1.5 Mbps. 3.2 Transceiver Clock Frequency TX2 has an on-chip oscillator circuit that uses an external 24-MHz (±100-ppm) crystal with the following characteristics: • Parallel resonant • Fundamental mode • 500-µW drive level • 27–33 pF (5% tolerance) load capacitors. An on-chip phase-locked loop (PLL) multiplies the 24-MHz oscillator up to 30/60 MHz, as required by the transceiver parallel data bus. The default UTMI interface clock (CLK) frequency is determined by the DataBus16_8 pin. 3.3 Buses The two packages allow for either 8- or 8/16-bit bidirectional data bus for data transfers to a controlling unit. The 48-pin package allows only 8-bit transfers while the 56-pin package adds an additional 8 bits to allow for a selection of 8- or 16-bit transfers. 3.4 Reset Pin An input pin (Reset) resets the chip. This pin has hysteresis and is active HIGH according to the UTMI specification. The internal PLL stabilizes approximately 200 µs after VCC has reached 3.3V. 3.5 Line State The Line State output pins LineState[1:0] are driven by combinational logic and may be toggling between the “J” and the “K” states. They are synchronized to the CLK signal for a valid signal. On the CLK edge the state of these lines reflect the state of the USB data lines. Upon the clock edge the 0-bit of the LineState pins is the state of the DPLUS line and the one bit of LineState is the DMINUS line. When synchronized, the set-up and hold timing of the LineState is identical to the parallel data bus. 3.6 Full-speed vs. High-speed Select The FS vs. HS is done through the use of both XcvrSelect and the TermSelect input signals. The TermSelect signal enables the 1.5 K ohm pull-up on to the DPLUS pin. When TermSelect is driven LOW, a SE0 is asserted on the USB providing the HS termination and generating the HS Idle state on the bus. The XcvrSelect signal is the control which selects either the FS transceivers or the HS transceivers. By setting this pin to a “0” the HS transceivers are selected and by setting this bit to a “1” the FS transceivers are selected. 3.7 Operational Modes The operational modes are controlled by the OpMode signals. The OpMode signals are capable of inhibiting normal operation of the transceiver and evoking special test modes. These modes take effect immediately and take precedence over any pending data operations. The transmission data rate when in OpMode depends on the state of the XcvrSelect input. Document #: 38-08016 Rev. *B Page 4 of 14 CY7C68000 OpMode[1:0] Mode 00 0 Normal operation Description 01 1 Non-driving 10 2 Disable Bit Stuffing and NRZI encoding 11 3 Reserved Mode 0 allows the transceiver to operate with normal USB data decoding and encoding. Mode 1 allows the transceiver logic to support a soft disconnect feature which three-states both the HS and FS transmitters, and removes any termination from the USB, making it appear to an upstream port that the device has been disconnected from the bus. Mode 2 disables Bit Stuff and NRZI encoding logic so 1s loaded from the data bus becomes Js on the DPLUS/DMINUS lines and 0s become Ks. 4.0 DPLUS/DMINUS Impedance Termination The CY7C68000 does not require external resistors for USB data line impedance termination or an external pull up resistor on the DPLUS line. These resistors are incorporated into the part. They are factory trimmed to meet the requirements of USB 2.0. Incorporating these resistors also reduces the pin count on the part. 5.0 Pin Assignments The following pages illustrate the individual pin diagrams, plus a combination diagram showing which of the full set of signals are available in the 48- and 56-pin packages. The 48-pin package is the lowest-cost version and provides an 8-bit, 60-MHz interface. The 56-pin package is the full version, offering an 8-bit (60-MHz) or 16-bit (30-MHz) bus interface. The two signals required for 16-bit operation are ValidH and DataBus16_8, and are present only in the 56-pin version. 48-pin FBGA A1 A2 A3 A4 A5 A6 AGND DMINUS DPLUS Reserved XTALOUT XTALIN B1 B2 B3 B4 B5 B6 AGND GND Reserved GND VCC AVCC C1 C2 C3 C4 C5 C6 CLK GND VCC VCC VCC AVCC D1 GND D2 GND D3 VCC D4 NC D5 RESET D6 TXVALID E1 RXVALID E2 RXACTIVE E5 E6 TERMSELECT XCVRSELECT SUSPEND TXREADY F1 OPMODE1 F2 Reserved F3 OPMODE0 F4 Reserved F5 Reserved F6 Reserved G1 G2 LINESTATE1 Reserved H1 H2 LINESTATE0 RXERROR E3 E4 G3 G4 G5 G6 D7 H3 D5 H4 D3 H5 D1 H6 D6 D4 D2 D0 Figure 5-1.

Indicates that the data bus is valid. The assertion of Transmit Valid initiates SYNC on the USB. The negation of Transmit Valid initiates EOP on the USB. The start of SYNC must be initiated on the USB no less than one or no more that two CLKs after the assertion of TXValid. In HS (XcvrSelect = 0) mode, the SYNC pattern must be asserted on the USB between eight and 16 bit times after the assertion of TXValid is detected by the Transmit State Machine. In FS (Xcvr = 1), the SYNC pattern must be asserted on the USB no less than one or more than two CLKs after the assertion of TXValid is detected by the Transmit State Machine. 8 E6 TXReady Output Transmit Data Ready. If TXValid is asserted, the SIE must always have data available for clocking in to the TX Holding Register on the rising edge of CLK. If TXValid is TRUE and TXReady is asserted at the rising edge of CLK, the CY7C68000 will load the data on the data bus into the TX Holding Register on the next rising edge of CLK. At that time, the SIE should immediately present the data for the next transfer on the data bus. 28 E1 RXValid Output Receive Data Valid. Indicates that the DataOut bus has valid data. The Receive Data Holding Register is full and ready to be unloaded. The SIE is expected to latch the DataOut bus on the clock edge. 29 E2 RXActive Output Receive Active. Indicates that the receive state machine has detected SYNC and is active. RXActive is negated after a bit stuff error or an EOP is detected. 30 H2 RXError Output Receive Error. 0 Indicates no error. 1 Indicates that a receive error has been detected. 7 – ValidH Document #: 38-08016 Rev. *B I/O Default Description ValidH. This signal indicates that the high-order 8 bits of a 16-bit data word presented on the Data bus are valid. When DataBus16_8 = 1 and TXValid = 0, ValidH is an output, indicating that the high-order receive data byte on the Data bus is valid. When DataBus16_8 = 1 and TXValid = 1, ValidH is an input and indicates that the high-order transmit data byte, presented on the Data bus by the transceiver, is valid. When DataBus16_8 = 0, ValidH is undefined. The status of the receive low-order data byte is determined by RXValid and are present on D0–D7. Page 8 of 14 CY7C68000 Table 5-1.

Uni_Bidi Default Description Data Bus 16_8. Selects between 8 and 16 bit data transfers. 1–16-bit data path operation enabled. CLK = 30 MHz. 0–8-bit data path operation enabled. When Uni_Bidi = 0, D[8:15] are undefined. When Uni_Bidi =1, D[0:7] are valid on RxValid and D[8:15] are valid on TxValid. CLK = 60 MHz Note that 16-bit operation is only an option for a HS/FS transceiver implementation.[2] Input Driving this pin HIGH enables the unidirectional mode when the eight-bit interface is selected. Uni_Bidi is static after power on reset (POR). VCC. Connect to 3.3V power source. Note: 2. DataBus16_8 is static after Power-on Reset (POR) and is only sampled by the macrocell on the negation of Reset.
