SP5301DS/10 SP5301 Universal Serial Bus Transceiver Copyright 2000 Sipex Corporation
The
SP5301
incorporates a receive error circuit.
This error circuit outputs CMOS signals on the
receive error pin (RERR) and the receive single
ended zero pin (RSE0) under specific conditions
from the USB bus. When OE is asserted LOW, it
enables the USB driver to transmit data on the D+
and D- output pins. The receive error circuit is
disabled in this condition and both RERR and
RSE0 are forced low. The receive error circuit is
activated in receive mode when OE is HIGH. The
receive error circuit will signal an error state
when both D+ and D- are HIGH by forcing RERR
HIGH. The receiver error circuit will signal a single
ended zero when both D+ and D- are LOW by
forcing RSE0 HIGH. A single ended zero is a
valid state and is used to signal an end of packet
(EOP) in signal transmission. (
CAUTION
: Since
both RERR and RSE0 are CMOS outputs, care
must be taken to ensure that RERR and RSE0
are
NOT
connected to V
CC
or GND.)
The
SP5301
has a suspend input pin (SUSPND)
which enables a low power state while the USB
bus is inactive. When SUSPND is asserted HIGH
or
SP5301
is in transmit mode (OE is LOW), the
receive data pin (RCV) will be forced LOW.
The
SP5301
can transmit and receive serial data
at both full speed, 12Mbps, and at low speed,
1.5Mbps, data rates. At full speed, the active
supply current of the
SP5301
is 6mA. In the
suspend state, the supply current is typically
20nA.
Full speed USB applications include ISDN,
PBX, POTS, sampled analog devices, audio,
printers, and telephony designs. Low speed USB
applications include locator devices, keyboards,
mouse, tablets, light pens, stylus, game
peripherals, virtual reality peripherals, and
monitor configurations. The USB protocol
provides full support for the real-time data
for voice, audio, and compressed video. The
SP5301
is specifically geared towards low-cost
USB solutions for the PC peripheral markets
Waveforms 1 and 2 below show device behavior
in transmit mode, at both low and full speed,
with the D+/D- pins driving the load specified
