DESCRIPTION
The SP530 is a half-duplex Universal
Serial Bus (USB) differential transceiver
that interfaces with the VHDL Serial
Interface Engine (SIE) from the USB
developer's conference. The SP530 is
designed to allow digital logic to communi-
cate with the physical layer of the
Universal Bus.
The USB is a cable bus that supports data
exchange between a host computer and
a wide range of peripherals. Attached
peripherals share USB bandwidth through
a host scheduled token based protocol.
The USB allows peripherals to be atached,
configured, used, and detached while the
host and other peripherals are in
operation. This is referred to as dynamic,
or hot, attachment and removal. USB
attributes include lower costs, hot plug-
and-play with dynamic attach-detach
capabilities, ease of design and use,
multiple peripherals, guaranteed latency,
and guaranteed bandwidth.
The USB is specified to be an industry
standard extension to the PC architecture
with a focus on Computer Telephony
Integration (CTI), consumer, and produc-
tivity applications. The architecture of the
USB protocol can ease the expansion
of PC peripherals, provide a low-cost
solution that supports tranfer rates up to
2Mbps, and can fully support real-time
data for voice, audio, and compressed
video.
The USB protocol can provide protocol
flexibility for mixed-mode isochronous data
transfers and asynchrounous messaging.
Guaranteed bandwidth and low latencies
are appropriate for many telephony and
audio applications. A 2Mbps bus covers
the mid-speed and low-speed data rang-
es. Typically, mid-speed data types are
isochronous and low-speed data comes
from interactive devices. Isochronous com-
munication can only be used by full speed
devices.
THEORY OF OPERATION
The USB protocol can support multiple
connections for up to 27 physical
devices composed of many diverse func-
tions. This makes the SP530 an ideal
solution for multidrop applications. This
lower protocol overhead results in high
bus utilization. An isochronous workload
may utilize the entire USB bus
bandwidth. The USB protocol reflects a
robust capability of dynamic insertion and
removal of devices identified in user
perceived real-time. This PC plug and
play quality preserves the marketable
synergy with the PC industry, being a
simple protocol to implement and
integrate into existing operating systems.
The SP530 contains a differential driver
and a differential receiver in a half-duplex
configuration. The driver is enabled by
the OE pin. If OE is asserted LOW,
the driver is active and the D- and D+
pins drive USB signals. The differential
receiver is also controlled by the OE pin.
If OE is HIGH, while SUSPEND is LOW,
the receiver is active and the driver is in
tri-state. In this receive mode, the D- and
D+ pins are now receiving USB signals.
The typical driver output voltage swing for
D- and D+ of the SP530 will be less than
+0.3V for the LOW state and greater than
+2.8V for the HIGH state.
The SP530 is a USB differential
interface with very high receiver input
sensitivity. This makes data virtually
immune to noise on the USB pipeline.
The ±90mV minimum receiver input
sensitivity of the SP530 ensures
recovery of even severely attenuated
signals.
