XCVRSEL[1]
Input
N/A
Transceiver Select. These signals select between
the FS and HS transceivers:
Transceiver select.
00: HS
01: FS
10: LS
11: LS data, FS rise/fall times
13
RXACTIVE
Output
High
Receive Active. Indicates that the receive state
machine has detected Start of Packet and is active.
14
OPMODE[1]
Input
N/A
Operational Mode. These signals select between
the various operational modes:
[1] [0] Description
0 0 0: Normal Operation
0 1 1: Non-driving (all terminations removed)
1 0 2: Disable bit stuffing and NRZI encoding
1 1 3: Reserved
15
OPMODE[0]
Input
N/A
16
CLKOUT
Output,
CMOS
N/A
60MHz reference clock output. All UTMI+ signals are
driven synchronous to this clock.
17
LINESTATE[1]
Output
N/A
Line State. These signals reflect the current state of
the USB data bus in FS mode. Bit [0] reflects the
state of DP and bit [1] reflects the state of DM. When
the device is suspended or resuming from a
suspended state, the signals are combinatorial.
Otherwise, the signals are synchronized to CLKOUT.
[1] [0] Description
0 0 0: SEO
0 1 1: J State
1 0 2: K State
1 1 3: SE1
18
LINESTATE[0]
Output
N/A
19
VDD1.8
N/A
N/A
1.8V regulator output for digital circuitry on chip.
Place a 0.1uF capacitor near this pin and connect
the capacitor from this pin to ground. Connect pin 19
to pin 34.
20
VDD3.3
N/A
N/A
3.3V PHY Supply. Provides power for Hi-Speed
Transceiver, UTMI+ Digital, Digital I/O, and
Regulators.
21
HOSTDISC
Output
High
Host Disconnect. Indicates that a downstream
device has been disconnected from this host PHY
when operating in HS host mode. Automatically
reset to 0b when Low Power Mode is entered.
