description
The TNETE211 interfaces the ThunderLAN TNETE100’s IEEE 802.3u media independent interface to an
IEEE 802.12 physical media-dependent device for 100VG-AnyLAN operation. The TNETE211 is responsible
for quartet channeling, scrambling the transmission data into five-bit data quintets, and encoding the resulting
quintets into six-bit (5B6B) symbols. The TNETE211 also adds the preamble, start-frame delimiter, and
end-frame delimiter to each channel.
Quartet channeling refers to the process of dividing the MAC frame data octets into five-bit data quintets and
alloting them sequentially among the four transmission pair channels. The data scrambler alters the five-bit
quintet into a randomized bit pattern which is helpful in reducing radio-frequency interference and signal cross
talk between channels. The 5B6B symbol encoding transforms the five-bit randomized pattern into
predetermined six-bit symbols. This provides a balanced data pattern with an equal number of zeroes and ones
for clock transition synchronization for receive circuitry. This symbol encoding also has the added benefit of
being an error-checking mechanism.
Compliant with IEEE Standard 1149.1-1990 (JTAG), the TNETE211 provides a five-pin test-access port that is
used for boundary-scan testing.
The TNETE211 is available in an 80-pin plastic quad flat package.

Pin Functions
Following is a list of TNETE211 physical media independent (PMI) pins and their functions. Assignment of pin
numbers follows the order necessary to allow ThunderLAN and IEEE 802.12-compliant PMD devices to be laid
out without any traces crossing. Pin names use the convention of indicating active low signals with an overbar.
All ThunderLAN signals begin with an M (for MII). All manufacturing test signals begin with a T (for Test). All
network interface signals begin with a P (for Physical Media Dependent).

O
Receive data. MRXD[0–3] represents the nibble receive data from the PMD front end. The PMI
indicates the priority of the incoming frames on these pins on the cycle before the assertion of MRXDV
(the cycle before frame reception begins). MRXD1 indicates the transmission priority of the received
frame. A value of zero indicates normal transmission, a value of one indicates priority transmission.
Data on these pins is always synchronous to MRCLK.
MRCLK
14
O
Receive clock. MRCLK is the receive clock source from the PMI front end.
MCRS

completeness.
Management data I / O. MDIO is the serial management interface to PMD chip.
MCOL
17
O
Collision sense. MCOL indicates that the PMI is transmitting on the physical media.
• MCOL (active low) is used to acknowledge a transmission request. TNETE100 must begin
frame transmission 50 MTCLK cycles after the assertion (low) of MCOL.
MCOL is held asserted low until the PMI has completed all transmission tasks.
MTXER

asserted, these pins carry data transmissions. When MTXEN is not asserted (frame transmission not
in progress), these pins carry control information.
• MTXD0 asserted (high) indicates TNETE100 is requesting frame transmission.
• MTXD1 indicates the transmission priority required. A value of zero indicates normal
transmission; a value of one indicates priority transmission.
Data/control on these pins is always synchronous to MTCLK.
MTCLK

PARAMETER MEASUREMENT INFORMATION
Outputs are driven to a minimum high-logic level of 2.4 V and to a maximum low-logic level of 0.6 V. These levels
are compatible with TTL devices.
Output transition times are specified as follows: For a high-to-low transition on either an input or output signal,
the level at which the signal is said to be no longer high is 2 V and the level at which the signal is said to be low
is 0.8 V. For a low-to-high transition, the level at which the signal is said to be no longer low is 0.8 V and the level
at which the signal is said to be high is 2 V, as shown below.
The rise and fall times are not specified but are assumed to be those of standard TTL devices, which are typically
1.5 ns.
