1 Introduction

The SMT401 is a TIM carrier in the form of a PCI Mezzanine Card (PMC). The board is equipped with a high bandwidth PCI interface, allowing it to be

hosted directly by any platform with a PCI bus (Revision 2.0 or later) conforming to the IEEE P1386 (Common Mezzanine Card) standard.

1.1 Specifications:

• Accepts standard size 1 C40/C44 TIM

• 32-bit 33MHz PCI interface including:

• Bus master global bus to PCI interface with 43 MB/s

sustained throughput

• Host comm-port interface with >10Mbytes/s performance

• Up to six unbuffered Sundance comm-ports

• External JTAG access with master and slave ports

• 3.3V available to TIM

2 Installation

This chapter explains how to attach the SMT401 to a PMC motherboard.

2.1 Handling Instructions

• Observe the usual precautions for preventing damage to components by

electrostatic discharge. Personnel handling the board should be earthed.

• Avoid flexing the board along its length.

2.2 Setting Up 3.3V Supply

The SMT401 can supply 3.3V to a TIM site using the two plated mounting holes next to the TIM sockets. The 3.3V can be supplied from the 3.3V pins on the PMC connector or from an on board regulator. This selection is made via JP2 as follows

Link 3.3V supply

JP2 pin1 – JP2 pin2 3.3V from regulator JP2 pin2 – JP2 pin3 3.3V from PMC connector

2.3 Installing a TIM onto the SMT401 Note: This operation should not be performed while the SMT401 is

powered up.

To install a TIM onto an SMT401, carry out the following procedure:

1. Place the TIM over the TIM sockets of the SMT401. Ensure that the TIM is oriented correctly, as otherwise it will not fit into the TIM sockets.

2. Apply sufficient but not excessive force to the TIM to push it firmly into the TIM sockets.

3. Secure the TIM with M2.5 nylon bolts and nuts, using the two holes next to the TIM connectors provided for this purpose. If the TIM requires 3.3V (Sundance C6x TIM modules) the supplied metal stand-offs and bolts should be used in place of the nylon nuts and bolts. The 3.3V is supplied via the plated mounting holes so it is essential that a good connection is made between the plated mounting hole and stand-off if the 3.3V supply is being used.

2.4 Installing the SMT401 onto a PMC carrier Note: This operation should not be performed while the PMC carrier is

powered up.

The SMT401 must be affixed to the PMC carrier in the way shown below, using the metal stand-offs, metal bolts and plastic washers provided:

3 Connectors

This chapter details the connectors on the SMT401.

3.1 Comm-ports

The SMT401 has connections for up to six comm-ports, but usually only there will only be five comm-ports available to the user, since one comm-port is dedicated to the host comm-port interface (see figure 1.1, page 7).

Figure 3.1 shows the locations of the various connectors, and which C4x comm-port they correspond to. C by the C40 TIM:

J11 is used as the Host Comm port and is not normally available for connection Figure 3-1: Comm-port Locations on SMT401

As with all C4x comm-ports, it is important to observe the rule governing the connection of RTO and RTI comm-ports:

Important Note

J10, J12, are RTO comm-ports

J11, J13 are RTI comm-ports

Do not connect a RTO comm-port to another

RTO comport

Do not connect a RTI comm-port to another RTI

Failure to observe these rules can result in

permanent damage.

3.1.1 Sundance Comm-ports (J10, J11, J12, J13, J14, J15)

Sundance compatible comm-ports can be used to make connections over short distances (30cm or less) to other Sundance comm-ports. The cables

should be fitted such that at one end, the blue insulation is face up, and at the other, the blue insulation is face down.

3.2 JTAG Input & Output Ports

Both input and output ports for JTAG are be provided, these are compatible with the SMT327 Compact PCI, SMT328 VME and other Sundance TIM carriers.

The JTAG interface is designed to operate at up to 10MHz across up to 4 SMT401 motherboards.

There is no re-timing at the TDO output of each board in order to provide a seamless chain of processors. This may limit the upper operating frequency of the JTAG controller. By default this frequency will be 8.33MHz (PCI_CLK/4) or less, depending on the PCI_CLK on the host.
