2 Hardware Installation 2 Introduction The following sections discuss the installation of the PMCspan modules and PMC modules.
2 Hardware Installation Installing PMC Modules PCI mezzanine card (PMC) modules mount on the PMCspan. Install the PMC modules on the PMCspan prior to installing the PMCspan onto the VME processor module. The PMCspan is keyed to accept only +5V PMC modules. Refer to the installation instructions that come with the PMC for any prerequisites. Dangerous voltages, capable of causing death, are present in this equipment. Use extreme caution when handling, testing, and adjusting.
2 Hardware Installation 4. Align the PMC module over the PMCspan. – Align the connectors on the underside of the PMC module with the corresponding connectors (J11, J12, and J14) on the PMCspan. – Align the keying hole on the PMC module with the keying pin on the PMcspan. 5. Gently press the PMC onto the PMCspan. – Turn the PMCspan component-side down. 6.
2 Hardware Installation Primary PMCspan To install a PMCspan module on your VME module, perform the following steps while referring to the figure on the next page: Dangerous voltages, capable of causing death, are present in this equipment. Use extreme caution when handling, testing, and adjusting. Warning Caution Note Inserting or removing modules with power applied may result in damage to module components. Avoid touching areas of integrated circuitry, static discharge can damage these circuits.
2 Hardware Installation Secondary PMCspan The secondary PMCspan mounts on top of a primary PMCspan module. To install on your VME module, perform the following steps while referring to the figure on the next page: Dangerous voltages, capable of causing death, are present in this equipment. Use extreme caution when handling, testing, and adjusting. Warning Caution Inserting or removing modules with power applied may result in damage to module components.
2 Hardware Installation 5. Attach the four standoffs from the secondary PMCspan mounting kit to the primary PMCspan by screwing the threaded male portion of the standoffs in the locations where the screws were removed in the previous step. 6. Place the secondary PMCspan on top of the primary PMCspan. Align the mounting holes in each corner to the standoffs and align the secondary PMCspan connector P3 with primary PMCspan connector J3. 7.
3 Functional Description 3 Introduction This chapter describes the physical and electrical structure of the PMCspan. Figure 3-1 and Figure 3-2 show the detailed block diagrams of the PMCspan and its primary interfaces. PMC module I/O is available through the PMCspan front panel opening (for PMC modules with front panel connectors) or through the PMCspan VMEbus P2 backplane connector. PCI-to-PCI Bridge Chip The primary component on the PMCspan is the PCI6150 PCI-to-PCI bridge chip.

3 Functional Description PMC Interface Each PMC slot has three EIA E700 AAAB connectors for a 32-bit PMC interface to secondary PCI bus and user specific I/O. The PMCspan VME backplane connector P2 provides 64 I/O signals for PMC 1, and 46 P2 I/O signals for PMC 2. Refer to Chapter 5, Connectors, for the pin signal assignments. PCI Expansion The PCI expansion interface is provided by a 114-pin plug connector (P4 or P5) on the secondary side of the PMCspan.
3 Functional Description PMC Performance All PMCspan models support 32-bit PCI operations at 33 MHz on the PMC (secondary) side. The PMCspan16E-002 primary carrier module supports 32-bit PCI operations on the processor (primary) side. Refer to the PCI6150 data book, listed in Appendix A, Related Documentation for PCI transaction timing information across the bridge. Writes to the PCI bus are also posted by the Raven chip ASIC, so this section will focus mainly on read cycles.
3 Functional Description Table 3-2 shows the ECC memory access latency for PMCspan-initiated cycles. Table 3-2.

The latency assumes two system clocks for 60X system bus arbitration. 2. The latency is based on 60ns, fast-page DRAM timing.

4 Programming Model 4 Introduction This chapter describes the programming model for the PMCspan. PLX PCI6150 Configuration Registers The PCI Configuration Registers for the PLX PCI6150 PCI-to-PCI Bridge chip are shown in Table 4-1. For a detailed register bit description, refer to the PLX PC16150 data book listed in Appendix A, Related Documentation.

4 Programming Model Table 4-2. Register 6-1 (PCIIDR; PCI:00h) PCI Configuration ID Bit Description Read Write Walue after Reset 15:0 Vendor ID, identifies PCI6150 manufacturer. Defaults to the PCISIG-issued PLX Vendor ID (3388h) if a blank or no serial EEPROM is present. Yes Only if RRC[7]=1;Seri al EEPROM 3388h 31:16 Device ID. Identifies the particular device.
4 Programming Model The PCI6150 forwards Type 1 to Type 0 configuration transactions as delayed transactions which are limited to a single data transfer. Table 4-3.
4 Programming Model The PCI6150 translates the Type 1 Configuration command to a Special Cycle and forwards the address and data unchanged. The transaction is forwarded as a delayed transaction but the target response is not forwarded back because Special Cycles result in a master abort. If more than one data transfer is requested during a Special Cycle, the PCI6150 responds with a target disconnect during the first data phase.
4 Programming Model PMC Clock, Request, Grant Assignment The PCI6150 bridge chip provide individual clock sources and arbitration logic for each PMC module on the secondary PCI bus. The PMCspan routes the secondary PCI bus Clock, Request and Grant signals between the PCI6150 bridge chip and the PMC slots as shown in Table 4-5. Table 4-5.
