Description
The 80220/80221 are highly integrated analog interface
IC's for twisted pair Ethernet applications. The 80220/
80221 can be configured for either 100 Mbps (100Base-
TX) or 10 Mbps (10Base-T) Ethernet operation. The
80220 is packaged in a 44L package, while the 80221 is
packaged in a 64L package and contains a few more
features.
The 80220/80221 consist of 4B5B/Manchester encoder/
decoder, scrambler/descrambler, 100Base-TX/10Base-T
twisted pair transmitter with wave shaping and output
driver, 100Base-TX/10Base-T twisted pair receiver with
on chip equalizer and baseline wander correction, clock
and data recovery, AutoNegotiation, controller interface
(MII), and serial port (MI).
The addition of internal output waveshaping circuitry and
on-chip filters eliminates the need for external filters nor-
mally required in 100Base-TX and 10Base-T applications.
The 80220/80221 can automatically configure itself for
100 or 10 Mbps and Full or Half Duplex operation with the
on-chip AutoNegotiation algorithm.
The 80220/80221 can access eleven 16-bit registers though
the Management Interface (MI) serial port. These registers
contain configuration inputs, status outputs, and device
capabilities.
The 80220/80221 are ideal as media interfaces for
100Base-TX/10Base-T adapter cards, motherboards, re-
peaters, switching hubs, and external PHY's.

40 50 REXT
— Transmit Current Set. An external resistor connected between this pin and GND will set the
output current level for the twisted pair outputs.
37 42 OSCIN I Clock Oscillator Input. There must be either a 25 Mhz crystal between this pin and GND or
a 25 Mhz clock applied to this pin. TX_CLK output is generated from this input.
29 34 TX_CLK O
Transmit Clock Output. This controller interface output provides a clock to an external
controller. Transmit data from the controller on TXD, TX_EN, and TX_ER is clocked in on
rising edges of TX_CLK and OSCIN.
35 40 TX_EN I Transmit Enable Input. This controller interface input has to be asserted active high to
indicate that data on TXD and TX_ER is valid, and it is clocked in on rising edges of TX_CLK
and OSCIN.
33 38 TXD3
32 37 TXD2
31 36 TXD1
30 35 TXD0
I Transmit Data Input. These controller interface inputs contain input nibble data to be
transmitted on the TP outputs, and they are clocked in on rising edges of TX_CLK and OSCIN
when TX_EN is asserted.
34 39 TX_ER / I
TXD4
Transmit Error Input. This controller interface input causes a special pattern to be
transmitted on the twisted pair outputs in place of normal data, and it is clocked in on rising
edges of TX_CLK when TX_EN is asserted.
25 26 RX_CLK O
If the device is placed in the Bypass 4B5B Encoder mode, this pin is reconfigured to be the
fifth TXD transmit data input, TXD4.
Receive Clock Output. This controller interface output provides a clock to an external
controller. Receive data on RXD, RX_DV, and RX_ER is clocked out on falling edges of
RX_CLK.
16 13 CRS
O Carrier Sense Output. This controller interface output is asserted active high when valid data
is detected on the receive twisted pair inputs, and it is clocked out on falling edges of RX_CLK.
17 14 RX_DV O Receive Data Valid Output. This controller interface output is asserted active high when valid
decoded data is present on the RXD outputs, and it is clocked out on falling edges of RX_CLK.
19 19 RXD3
20 20 RXD2
21 21 RXD1
22 22 RXD0
O Receive Data Output. These controller interface outputs contain receive nibble data from
the TP input, and they are clocked out on falling edges of RX_CLK.
