FASTPULSE MediaCAT (Chip And Transformer) is a transceiver
component kit which enables the design of high performance, low-
cost frontends for high speed LAN products. MediaCAT consists of
Features
• High performance twisted pair transceiver solution
a monolithic twisted pair transceiver which implements the core • Flexible frontend kit for 100Base-TX, ATM 155 & TP-FDDI
Transmit/Receive signal processing and a matched magnetic mod-
ule which provides the wideband transformer coupling and EMI
filtering. The MediaCAT transceiver forms the analog interface
• Full compliance with PMD standards IEEE, ANSI and ATM
• Supports 100m of Unshielded Twisted Pair (UTP), Category 5 DataShee
between the digital PHY controller and the twisted pair cable
or Shielded Twisted Pair (STP) cable
(UTP-5 or STP). The matched nature of the devices anDdaptraoSvehneet4U.com
performance reduces the design effort and risk of implementing
100 Mbps+ frontends.
Employing FASTPULSE technology, the MediaCAT transceiver
PE-95000/10 incorporates transmit conditioning, receiver adaptive
equalization to compensate for cable losses and baseline restora-
tion to correct DC drifts in receiver datastream. The two key
MediaCAT IC
• Integrates high performance and programmable adaptive
equalizer
• Integrates compliant base line wander correction circuitry
• Versions for MLT3 and binary operation
encode/decode schemes which the ICs can implement are MLT3
(PE-95000) and Binary (PE-95010). MLT3 is a three level coding
scheme which is used in TP-FDDI and 100Base-TX applications to
support 125 Mbaud (100 Mbps) data transmission over 100 m of
• Programmable drive current
• Direct interface to PHY controllers
• EMC optimized design — edge rate control, CMRR
shielded (STP) or unshielded twisted pair (UTP) Category 5 cable • BiCMOS device/PLCC28 package
(2 pair). Binary coding (NRZ) is used principaly for
ATM 155 Mbps applications, to support 155 Mbps transmission
over 100 m STP or UTP Category 5 cable. The device has
a high degree of flexibility to allow it to be used in various standard
MediaCAT Magnetics
• Integrated transformer/choke device — tuned to MediaCAT IC
applications and to enable performance tailoring for customer
specific requirements.
• Provides TX/RX wide bandwidth isolation and EMI filtering
• SMD package for IR reflow compatibility
The PE-68517L is an integrated magnetic module device designed
for TP-FDDI, 10/100Base-TX and ATM155 Mbps applcations. It Applications
provides a balanced, wideband transformer with dual common
mode chokes to minimize EMI emissions. The device charac-
teristics are tuned to the MediaCAT transceiver resulting in an
• Network adapter cards (ISA, PCI, VME etc.)
• Hubs or concentrators
optimized device pair. For certain 10/100 Mbps applications the
PE-69016 provides the 10 Mbps and 100 Mbps magnetic interface
with integrated passive mixer.
MediaCAT devices meet or exceed the electrical specifications of
the following standards: ANSI X3.263 TP-PMD for TP-FDDI, IEEE
• Motherboards (PC, workstation, industrial)
• Bridges, routers, switches
• Switch uplink modules
• Point to point links (Telecom)
802.3u for Fast Ethernet 100Base-TX and ATM-UNI-PMD STS3c • Peripherals: storage, print servers, etc.
for ATM 155 Mbps applications.

NOTES:
1. ZEQP/N: The RC network between these pins sets a
frequency dependent gain which is increased linearly
from zero to maximum as the equalization level
increases from minimum to maximum.

4. CDEL: The capacitor at CDEL delays assertion of
the SD signal to allow the equalizer to stabilize.
Max assert time (us)=C(EQGAIN)(nF)X40 +

5. ENCSEL: TTL compatible CMOS selection pin of
encode/decode mode. High = Binary, Low = MLT3.
6. TXREF: Resistor controls the amplitude of the cur-
rent outputs, which determines the transmit signal
voltage amplitude. For the total system (Chip +
Transformer), the resistor value can be determined
as follows: R(TXREF) = (20 x Zcable) / Vpp where
Vpp = peak-peak differential amplitude (line output)
(V) Zcable = Characteristic differential cable
impedance
7. EQREF: The resistor at EQREF pin sets internal ref-
erence currents for the receiver circuitry.

8. COFF: Capacitor determines time constant of

9. EQGAIN: Indicates gain factor of equalizer. The
capacitor at this pin determines the maximum SD
deassert time. Maximum deassert time (us) =
C(EQGAIN) (nF) x 20
10. REQP/N: The resistor at REQP/N sets the minimum
signal gain through the equalizer.
