78Q21x3-DB MicroPHYTM
MII Evaluation Board
DEMO BOARD MANUAL
April 2007
DESCRIPTION
The 78Q21x3-DB is a design example for a
10/100BASE-TX Mbit/second Fast Ethernet MII
Interface adaptor. A 78Q2123 or 78Q2133
MicroPHY transceiver from Teridian provides the
network physical interface and MII (Medium
Independent Interface) interface.
Teridian Semiconductor’s MicroPHY is an auto-
sensing, auto-switching 10/100BASE-TX Fast
Ethernet transceiver with full duplex operation
capability. The device interfaces directly to the
IEEE-802.3u MII port.
Full-featured MII
management functions are included along with an
extended register set. The MicroPHY five bit PHY
address is defaulted to 0x001. The MicroPHY
interfaces to CAT5 UTP cable via a 1:1 transformer.
The transceiver’s transmitter includes on-chip the
pulse shaper and low power line driver. The
receiver incorporates a sophisticated combination of
real-time adaptive equalization, an adaptive DC
offset adjustment circuit and baseline wander
correction. Smart squelch circuitry further improves
the receiver’s noise rejection. Full featured auto-
negotiation or parallel detect modes are supported.
The demo board requires operation with a +3.3V
power supply.
