Introduction
The VMIPMC-5790 is an Dual-Channel Ultra160 SCSI Host Adapter built around the
LSI Symbios® SYM53C1010 highly integrated PCI Dual-Channel Ultra160 SCSI
controller. The IC is ideal for embedded applications that require high throughput.
The VMIPMC-5790 maximizes throughput while minimizing transfer latency and
host processor overhead. The host BIOS configures the VMIPMC-5790 as two
independent Ultra160 SCSI channels.
The two independent Ultra160 channels support wide Ultra160 SCSI synchronous
transfer rates up to 160 Mbyte/s on a Low Voltage Differential (LVD) SCSI bus.
Integrated LVDlink™ transceivers support both LVD and single-ended signals with
no external transceivers required. Fast SCSI, Ultra SCSI, Ultra2 SCSI, and Ultra160
SCSI are all supported by the VMIPMC-5790. The 8 Kbyte of internal RAM per
channel for SCRIPTS™ instruction storage allow all accesses to remain internal,
reducing the time spent on the PCI bus. A 944-byte DMA FIFO on each channel
allows the VMIPMC-5790 to efficiently burst up to 512 bytes across the PCI bus. SCSI
bus phase mismatches are handled in SCRIPTS, reducing CPU utilization.
Ultra160 SCSI Hardware Features:
• 64-bit, 33/66 MHz PCI interface
• No external memory required
• Double transition clocking for 160 Mbyte/s throughput on each channel
• 64-bit addressing supported through Dual Address Cycles (DACs)
• Complaint with PCI 2.2, PCI Power Management 1.1 and PC99
• Cyclic Redundancy Check (CRC)
• Domain validation
• Asynchronous Information Protection (AIP)

Functional Description
The VMIPMC-5790 Dual-Channel Ultra160 SCSI Host Adapter incorporates the
Symbios® SYM53C1010, which is a highly integrated PCI Dual-Channel Ultra160
SCSI controller. The SYM53C1010 is 100 percent compatible with the Ultra160 SCSI
initiative and provides additional features that ensure robust Ultra160 system
operation. Fast SCSI, Ultra SCSI, Ultra2 SCSI and Ultra160 SCSI are all supported by
the SYM53C1010. Double transition clocking enables throughput of up to
160 Mbyte/s on each channel for a total of 320 MBps, without increasing the interface
clock rate.
The SYM53C1010 uses the same proven CRC algorithm used by FDDI, Ethernet and
Fibre Channel, and detects all single bit errors, double bit errors, odd number of
errors, and all burst errors up to 32 bits long. To provide complete end-to-end
protection of the SCSI I/O, AIP protects all non-data phases, augmenting the CRC
feature of Ultra160. SureLINK™ domain validation technology detects the
configuration of the SCSI bus and automatically tests and adjusts the SCSI transfer
rate to optimize inter-operability. The SYM53C1010 controller and Ultra160 provide
Basic (Level 1) and Enhanced (Level 2) domain validation, while the SYM53C1010 has
an added feature of Margining (Level 3) domain validation. Figure 1 on page 16
shows the functional block diagram for the SYM53C1010.

Overview

PCI Interface
The Ultra160 SCSI PCI Interface complies with PCI Local Bus Specification Revision 2.2,
and implements a 64-bit/66 MHz PCI bus. It is backward compatible with 32-bit/33
MHz buses. The SYM53C1010 is a true PCI multifunction device in that it presents
one electrical load to the PCI bus. It uses one REQ/-GNT/pair to arbitrate for PCI bus
mastership, and separate interrupt signals are generated for SCSI Function A and
SCSI Function B for maximum performance. The SYM53C1010 complies with PCI
Power Management Interface Specification Revision 1.1 and PC 99, supporting power
states D0, D1, D2, D3hot and D3cold, power management capabilities registers, and
programmable values for PCI Subsystem Vendor ID and Subsystem ID. Extended
access cycles (Memory Read Line, Memory Read Multiple, and Memory Write and
Invalidate) are also supported.
Ultra160 SCSI Memory
The SYM53C1010 supports up to 1 Mbyte of external expansion ROM through a
parallel interface. For ease of software development and field upgrades of the ROM,
the interface supports local programming of FLASH memory. A serial 2-wire interface
on each SCSI channel provides a connection to an external serial EEPROM for storing
the Subsystem Vendor ID and Subsystem ID.
Ultra160 SCSI Processor
The SYM53C1010 provides two independent Ultra160 SCSI controllers on a single
chip. Each controller supports wide Ultra160 SCSI synchronous transfer rates up to
160 Mbyte/s on aLVD SCSI bus. Integrated LVDlink™ transceivers support both LVD
and single-ended signals withno externaltransceivers required. Fast SCSI, Ultra SCSI,
Ultra2 SCSI and Ultra160 SCSI are all supported by the SYM53C1010. An on-chip
SCSI clock quadrupler allows the chip to achieve Ultra160 SCSI transfer rates with an
input frequency of 40 MHz. The 8 Kbytes of internal RAM per channel for SCRIPTS
instruction storage allow all accesses to remain internal, reducing the time spent on
the PCI bus. A 944-byte DMA FIFO on each channel allows the device to efficiently
burst up to 512 bytes across the PCI bus. SCSI bus phase mismatches are handled in
SCRIPTS, reducing CPU utilization.
Ultra160 SCSI Termination
All SCSI buses require a termination network at each end to function properly.
Specific termination requirements differ, depending on which types of SCSI devices
are present on the bus. The SCSI Host Adapter uses the UCC5630A termination ICs to
automatically sense the SCSI bus and switch the termination to either single ended
(SE) or low voltage differential (LVD) SCSI, dependent on which type of devices are
connected to the bus. The UCC5630A termination IC is used in multi-mode active
termination applications, where single ended (SE) and low voltage differential (LVD)
devices might coexist. The UCC5630A has both SE and LVD termination networks
integrated into a single monolithic component. The correct network is automatically
determined by the SCSI bus “DIFSENS” signal. The SCSI bus DIFSENS signal line is
used to identify which types of SCSI devices are present on the bus. On power-up, the
UCC5630A DIFSENS drivers will attempt to deliver 1.3V to the DIFSENS line.

If only LVD devices are present, the DIFSENS line will be successfully driven to 1.3 V
and the terminators will configure for LVD operation. If any single ended devices are
present, they will present a short to ground on the DIFSENS line, signaling the
UCC5630A(s) to configure into the SE mode, accommodating the SE devices. Or, if
any high voltage differential (HVD) devices are present, the DIFSENS line is pulled
high and the terminator will enter a high impedance state, effectively disconnecting
from the bus. Header E1 pins 3 & 4 enables automatic termination on the SCSI Host
Adapter to disable the termination remove the shorting strap.
Media Connection
The VMIPMC-5790 supports dual 68-pin VHDCI external connectors.
