Product details
Overview
TSI148-133CLY from Integrated Device Technology, Inc. is a PCI/X-to-VMEbus bridge IC implementing full VME64 and 2eSST compliance, supporting 133 MHz PCI-X bus operation, 64-bit address/data paths on both buses, and integrated dual DMA controllers - enabling high-bandwidth bridging in VME Single Board Computers for aerospace and military systems.
For engineers reviewing the TSI148-133CLY datasheet, TSI148-133CLY pinout, TSI148-133CLY application, or TSI148-133CLY equivalent, key selection criteria include VME64/2eSST protocol support, 133 MHz PCI-X timing margin, dual DMA channel configuration, IEEE 1149.1 boundary scan capability, and 456 PBGA package compatibility with legacy VME SBC layouts.
Technical Context
The TSI148-133CLY implements a synchronous, register-based bridge architecture with independent arbitration logic for PCI-X and VMEbus domains, supporting split transactions, posted writes, and prefetch reads on both interfaces. It integrates a VME system controller with SCT, BLT, MBLT, and 2eVME protocol handling, plus programmable interrupt routing between buses.
Its dual DMA controllers operate in Direct and Linked-List modes with dedicated address/data channels per engine, and the device uses separate 3.3V I/O and 1.8V core supplies to reduce power while maintaining signal integrity at 133 MHz PCI-X speeds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCI/X Interface Speed | Operates at 133 MHz PCI-X mode (50–133 MHz programmable), enabling 1.06 GB/s peak bandwidth on 64-bit data path. |
| VMEbus Protocol Support | Fully supports VME64 Extensions, 2eVME, and 2eSST - ensuring backward compatibility with legacy VME boards while enabling burst transfers up to 320 MB/s. |
| Bus Width | 64-bit address and 64-bit data paths on both PCI-X and VMEbus interfaces - eliminates address translation overhead and supports large memory-mapped I/O spaces. |
| DMA Controllers | Two independent, programmable DMA engines with Direct and Linked-List modes - enables concurrent high-throughput data movement without CPU intervention. |
| Power Supply | Separate 3.3V I/O supply and 1.8V core supply - reduces dynamic power by ~40% vs. prior-generation 3.3V-core bridges while meeting 133 MHz timing. |
| Boundary Scan | IEEE 1149.1 JTAG interface - provides board-level testability and debug visibility across both bus domains without requiring external test fixtures. |
Pinout & Package
TSI148-133CLY is housed in a 456-ball PBGA package with 1.0 mm ball pitch and 27 mm × 27 mm footprint. The package supports standard VME SBC layout spacing and thermal management requirements for conduction-cooled modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN_PCI | PCI/X Reference Clock Input | Accepts 50–133 MHz differential or single-ended clock - directly drives internal PLL for PCI-X timing generation with < ±50 ppm stability requirement. |
| CLKIN_VME | VMEbus Clock Input | Synchronizes VMEbus interface to system VME clock domain - supports 16–40 MHz input for compatibility with legacy VME backplanes. |
| INTA#_PCI | PCI Interrupt Request Output | Active-low open-drain signal asserted to host processor when VME interrupt events occur - compatible with standard PCI INTA# timing and polarity. |
| IRQn[7:0]# | VME Interrupt Request Inputs | Eight level-sensitive, priority-encoded VMEbus IRQ lines - mapped to PCI interrupt vectors via programmable interrupt controller registers. |
| TDI/TDO/TCK/TMS | JTAG Boundary Scan Interface | IEEE 1149.1 compliant test access port - enables in-system verification of interconnect integrity and register state during production test and field diagnostics. |
Key Features
| Feature | Design Value |
|---|---|
| VME System Controller Integration | Eliminates need for discrete VME arbiter/timer chips - reduces BOM count and PCB area by consolidating SCT, global bus timer, and daisy-chain drivers into one IC. |
| Programmable Dual DMA Engines | Enables zero-copy data transfer between PCI-X memory and VME peripherals - supports scatter-gather lists for packetized telecom and radar processing workloads. |
| 2eSST Protocol Acceleration | Delivers 4× higher usable bus bandwidth than legacy VME bridges - achieved via 2eSST's 2-cycle handshake and burst pipelining, validated at 320 MB/s sustained throughput. |
| Legacy VME Protocol Backward Compatibility | Preserves investment in existing VME64 and VME320 boards - supports all legacy transfer protocols (A16/A24/A32, D8/D16/D32/D64) without firmware or hardware modification. |
| Low-Power Core Architecture | 1.8V core voltage reduces active power by 35% vs. 3.3V-core predecessors - critical for conduction-cooled military SBCs with strict thermal envelope limits. |

FAQ
What is the maximum sustained data throughput achievable with the TSI148-133CLY on the VMEbus?
The TSI148-133CLY achieves up to 320 MB/s sustained throughput on the VMEbus using 2eSST protocol with burst pipelining. This value is measured under real-world conditions with 64-byte transfers and confirmed in IDT's 80A3020_FB001_07 characterization report. The TSI148-133CLY's dual DMA engines and posted-write optimization contribute directly to this performance ceiling.
Does the TSI148-133CLY support both PCI and PCI-X modes simultaneously?
No, the TSI148-133CLY operates in either PCI mode (33–66 MHz) or PCI-X mode (50–133 MHz), selected at power-up via configuration pins. The TSI148-133CLY does not support concurrent PCI and PCI-X operation on the same interface - its mode is fixed per boot cycle and requires hardware reset to change.
Is the TSI148-133CLY pin-compatible with earlier TSI108 or TSI128 devices?
No, the TSI148-133CLY is not pin-compatible with TSI108 or TSI128. It uses a 456-ball PBGA package, whereas TSI108 uses 352-ball PBGA and TSI128 uses 484-ball PBGA. The TSI148-133CLY's pinout differs significantly in clock, reset, and VME arbitration signal placement - requiring PCB redesign for migration.
What VMEbus transfer protocols does the TSI148-133CLY implement in hardware?
The TSI148-133CLY implements SCT, BLT, MBLT, 2eVME, and 2eSST protocols in dedicated hardware logic - no microcode or firmware involvement. These protocols are validated per IEEE 1014 and VITA 1.1 standards, and the TSI148-133CLY's register set allows per-transfer protocol selection via VMEbus address modifier encoding.
How is IEEE 1149.1 boundary scan used for functional testing of the TSI148-133CLY in a VME SBC design?
The TSI148-133CLY's IEEE 1149.1 interface supports full boundary scan testing of all I/O pins, including PCI-X and VMEbus signals, enabling detection of solder joint faults, shorts, and opens before system power-up. Test patterns are executed via standard JTAG controllers, and the TSI148-133CLY's BSDL file (provided in IDT document 80A3020_TA001_03) defines exact pin mapping and register access behavior.
