FUNCTIONAL DESCRIPTION
3•4 MPC8260ADS
The MPC8260ADS is meant to serve as a platform for S/W and H/W development around the MPC8260.
Using its on board resources and its associated debugger, a developer is able to load his code, run it, set
breakpoints, display memory and registers and connect his own proprietary H/W via the CPM expansion
connectors (P1 and P2 on the MPC8260TCOM), to be incorporated to a desired system with the MPC8260
device.
3•5 Ethernet. - 100BASE-TX and 10BASE-T
Two Fast-Ethernet modules used FCC1 (FE_1) and FCC3 (FE_2) are on this board, together with the Fast
Ethernet on the ADS board it will be possible to run 3 Fast Ethernet modules at the same time or it is
possible to disable each one of them to let the user to use the FCC’s for other uses. The disable can be
done by the MDIO bus. The device that use to perform the transceiver operation is the Level One LXT970.
The LXT970 is an IEEE 802.3 compliant 10/100Mbps Fast Ethernet PHY Transceiver that directly supports
both 100BASE-TX and 10BASE-T applications. Provides a Media Independent Interface (MII) for easy
attachment to 10/100 Media Access Controller (MAC)s. The LXT970 supports full-duplex operation at 10
and 100 Mbps. Its operating condition can be set using autonegotiation panel detection or manual control.
The configuration of the LXT970 can be controlled via the MII serial port (MDIO Interface). This interface
allows upper-layer devices to control or monitor the LXT970. The LXT970 can also be controlled via
external pin settings (Hardware Control Interface). This option is not supported on the 8260TCOM.
The LXT970 is connected to the MPC8260 via the FCC1 and FCC3 that performs MII interface through
the I/O ports.

3•6 DS3 (T3).
Two DS3 modules are on this board; they use the TDMA1 (FCC2) and TDMA2 (FCC3). Each one of the
DS3 module is composed of Framer and Line Interface Unit. The DS3 Framer is TRAN-SWITCH TXC-
03401. It is a 5V device. The MPC8260 device is a 3.3V device. That is why a 5V to 3.3V translator is
needed in the output direction from the framer, to bridge between the DS3F, (5V) to the MPC8260 (3.3V)
The device used is a 74LXT541.
The DS3F is designed for DS3 framer applications in which broadband payloads are mapped into the
44.736 Mbit/s DS3 frame format. The payload interface is nibble-parallel format.
The Line Interface Unit is a TRAN-SWITCH TXC-20153G, this LIU is a module which include the
transformer and the TRAN SWITCH TXC-02020 LIU device. It connected from one side to the DS3F and
from the other side to BNC connector. It is a 5V device.
Each one of the DS3 module can be isolated by a logic control to let the user to use FCC2 and FCC3 for
other purposes.
The DS3 Line Interface Module (DS3LIM-SN) is a complete and compact full duplex analog line to digital
terminal interface. It converts B3ZS - encoded line signals, in either DS3 asynchronous, to and from NRZ
data and clock signals, in addition to the synchronous signal option.
In order to enable DS3_1, PD4 (T1_1) & PD18 (T1_7) & PD19 (T1_8) should be high -’1’ and then drive
PD25 to be low -’0’. In order to enable DS3_2, PD6 (T1_3) & PD7 (T1_4) & PD8 (T1_5) & PD19 (T1_8)
should be high -’1’ and then drive PA4 to be low -’0’. Each one of the DS3 module has a led to light when
this DS3 module is enable, LD13 for DS3_2 and LD16 for DS3_1. Each DS3 modules also has a Frame
Error and Receive signal loss leds.
Each one of the DS3 module have two loopback capabilities for testing transmit and receive loopback via
the loopback controls block of the TXC-20153G.
Transmit - to - Receive loopback connects the data path from the transmit I/O control block output to the
receive I/O control block input, and disable the external receiver input.
Transmit - to - Receive loopback is activated by placing a low on the TR signal pin.
Receive - to Transmit loopback connects the receive data output path to the transmit input circuits and
disable the NRZ transmit input.

The physical control to the RT, TR signals of both DS3 modules are controlled as follow:
DS3_1 RT will be low if PA5 and PA1 will be low. (if PA1 is high there is no loop back at all)
DS3_1 TR will be low if PA5 will be high and PA1 will be low. (if PA1 is high there is no loop back at all)
DS3_2 RT will be low if PC13 and PA1 will be low. (if PA1 is high there is no loop back at all)
DS3_2 TR will be low if PC13 will be high and PA1 will be low. (if PA1 is high there is no loop back at all)

3•7 T1
The T1 is a 1.544Mhz serial line; this board can handle up to 8 T1 line simultaneously. All the T1 modules
on this board are composed by one PM4388 (Framer), 2 PM4314 (LIU) and 2 ST5170 transformers. The
PM4388 device includes 8 T1 framers, each framer in this device can be controlled by its own internal
registers. The PM4388 controlled by the MPC8260 data and address bus. It gets its chip select signal from
the control logic. The PM4314, which is a quad line interface unit, is connected from one side to the framer,
PM4388, and from the other side to the line transformer. Each one of the T1 line interface units can be also

controlled by the internal registers. This device is also connected to the MPC8260 by the address and data
bus. It gets it’s chip select signal from the control logic. The ST5170 includes a 4 transformers, each one
of the ST5170 connected to one PM4314 device.
Each one of the MPC8260 T1 group of signals can be isolate from the framer by buffer. (The PM4388
device can not isolate independently one of the eight T1 signal group). T1_1,2,3,4 modules can be isolated
by PD4-PD7. ’0’ on these signals enables each T1 interface. The T1-5,6,7,8 modules can be isolated by
PD8, PD9, PD18 and PD19. ’0’ on these signals enables each T1 interface. 8 leds are placed on the board
to show which one of the T1 port is enable. Each led lights depend upon the enable T1 signal, for example
if PD4 will be low LD24 (T1_1 enable) will light.
Together with the 8260ADS board it will be possible to operate the8xT1andATM155Mbps or Fast
Ethernet over FCC1.
3•8 Control Logic.
The control logic allows the user to disable each one of the following elements: 8 x T1, 2 x DS3 and 4 x
DS3 loopback options. Although each one of the T1 is enabled directly from the MPC8260, all the T1
enable signals insert to the logic control, in order to disable a DS3 module that share some signal(s) as
T1_x. If one of the T1 enable and it share the same signals as one of the DS3, the appropriate DS3 will be
disable.
Each one of the Fast-Ethernet modules connected to FCC1,FCC2 and FCC3 (on the 8260TCOM or on the
8260ADS) is controlled via the MDIO and MDC signals (PC10, PC9); the SW should be aware that
enabling the Fast Ethernet without disabling the corresponding element that share the same GPIO signals
will damage the board. FE1 share the signals as the ATM module on the ADS, FE0 (the one that is placed
on the 8260ADS) share some of the T1_8, T1_7, T1_6 and T1_5. FE2 share some of the signals of T1_6,
T1_5, T1_4 T1_3
In order to use DS3 the SW should drive PD25 for DS3_1 (FCC2) to low or PA4 for DS3_2 (FCC3) to low.
If no one of the T1 that share the same signal of the desire DS3 is enable, the DS3(x) will be enable. The
user should disable the appropriate T1 channel if the appropriate T1 channel will not be disable the DS3
will not be enable. DS3(1) share the same signals with T1_1, T1_7 and T1_8, DS3(2) share the same
signals with T1_8, T1_5, T1_4, T1_3.
In addition to the above GPIO control signal from the MPC8260 the 8260TCOM Board use PA1, PA5 and
PC13 to select 4 types of DS3 loop-back as describe in the DS3 description paragraph.
The logic control select each one of the following devices by asserting it’s Chip Select signal, The ADS
drive two CS signals to the TCOM CS6 and CS7 called CSBRD1 and CSBRD2.

8260TCOM board (ground, 3.3V and 5V).
3•10 Ports Selection
The following table shows all the ports that are used on the 8260TCOM. It includes there function for each
used module. The table includes:
1. The port column, i.e. the port number.
2. The module name function which contains the 8 T1 ports (8 column).
3. The ATM 8 bit port on the ADS (this column is a dark column to accent the ADS function which uses
FCC1); each named cell of the column describes the function.
4. The Fast Ethernet address ’1’ column use FCC1.
5. The Fast Ethernet address ’0’ column which is also a dark one since it is on the ADS; it use FCC2.
6. The Fast ethernet address ’2’ column use FCC3.
7. The DS3 _1 column use FCC2.
8. The DS3_2 column use FCC3.
nc...
, I
or
In each table row there are I or O signs at the right side of the function name meaning that this signal is an
output from the MPC8260 device (O) or an input to the MPC8260 (I). In some rows there are several I/O
signs which mean the respective port can be use for several function. The user should avoid conflicts; as
an example if the ATM is used on the ADS it is not possible to use the FE address 1. This table can help
the user to define the desire module without having a conflict, or if there is a problem in the definition the
user can know which one of the module can cause the problem.
PC9 and PC10 are the MII MDIO and MDC signals; these signals are common to the 3 FE modules - the
one on the ADS and the two on the TCOM.
