EZ-USB TX2 Features
1.0
The Cypress EZ-USB TX2 is a Universal Serial Bus (USB) specification revision 2.0 transceiver, serial/deserializer, to a parallel
interface of either 16 bits at 30 MHz or eight bits at 60 MHz. 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.

3.1
Functional Overview
USB Signaling Speed
TX2 operates at two of the rates defined in the USB Specification 2.0, dated April 27, 2000:
• Full speed, with a signaling bit rate of 12 Mbps
• High speed, with a signaling bit rate of 480 Mbps.
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.

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.

TXValid
Input
Transmit Valid. 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.

Transmit Data Ready. If TXValid is asserted, the SIE must always have data

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.

ValidH. This signal indicates that the high-order 8 bits of a 16-bit data word

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.

Note that 16-bit operation is only an option for a HS/FS transceiver implementation.[2]

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:
