MOTOROLA ANALOG IC DEVICE DATA
The Motorola 10BASE–T transceiver, designed to comply with the ISO
8802–3 [IEEE 802.3] 10BASE–T specification, will support a Medium
Dependent Interface (MDI) in an embedded Media Attachment Unit (MAU)*.
The interface supporting the Data Terminal Equipment (DTE) is TTL, CMOS,
and raised ECL compatible, and the interface to the Twisted Pair (TP) media
is supported through standard 10BASE–T filters and transformers.
Differential data intended for the TP media is provided a 50 ns pre–emphasis
and data at the TP receiver is screened by Smart Squelch circuitry for
specific threshold, pulse width, and sequence requirements.
Other features of the MC34055 include: Collision and Jabber detection
status outputs, select mode pins for forcing Loop Back and Full–Duplex
operation, a Signal Quality Error pin for testing the collision detect circuitry
without affecting the TP output, and a LED driver for Link Integrity status. An
on–chip oscillator, capable of receiving a clock input or operating under
crystal control, is also provided for internal timing and driving a buffered
clock output.
The MC34055 is manufactured on a BiCMOS process and is packaged in
a 24 pin SOIC.
