Features
„ 128-pin TQFP lead-free package
„ 1394a-2000 OHCI link and PHY core function in a single
device:
— Single-chip link and PHY enable smaller, simpler,
more efficient motherboard and add-in card designs
— Enables lower system costs
— Leverages proven 1394a-2000 PHY core design
— Demonstrated compatibility with current Microsoft
Windows^® drivers and common applications
— Demonstrated interoperability with existing, as well as
older, 1394 consumer electronics and peripherals
products
— Feature-rich implementation for high performance in
common applications
— Supports low-power system designs (CMOS imple-
mentation, power management features)
— Provides LPS, LKON, and CNA outputs to support
legacy power management implementations
„ OHCI:
— Complies with the 1394 OHCI 1.1 Specification
— OHCI 1.0 backwards compatible—configurable via
EEPROM to operate in either OHCI 1.0 or OHCI 1.1
mode
— Complies with Microsoft Windows logo program
system and device requirements
— Listed on Windows hardware compatibility list
http://www.microsoft.com/hcl/results.asp
— Compatible with Microsoft Windows and MacOS ^®
operating systems
— 4 Kbyte isochronous transmit FIFO
— 2 Kbyte asynchronous transmit FIFO
— 4 Kbyte isochronous receive FIFO
— 2 Kbyte asynchronous receive FIFO
— Dedicated asynchronous and isochronous descriptor-
based DMA engines
— Eight isochronous transmit contexts
— Eight isochronous receive contexts
— Prefetches isochronous transmit data
— Supports posted write transactions
— Supports parallel processing of incoming physical
read and write requests
— Supports notification (via interrupt) of a failed register
access
— May be used without an EEPROM when the system
BIOS is programmed with the EEPROM contents.
„ 1394a-2000 PHY core:
— Compliant with IEEE ^® 1394a-2000, Standard for a
High Performance Serial Bus (Supplement)
— Three fully compliant cable ports, each supporting
400 Mbits/s, 200 Mbits/s, and 100 Mbits/s traffic
— Supports extended BIAS_HANDSHAKE time for
enhanced interoperability with camcorders
— While unpowered and connected to the bus, will not
drive TPBIAS on a connected port even if receiving
incoming bias voltage on that port
— Does not require external filter capacitor for PLL
— Supports link-on as a part of the internal
PHY core-link interface
— 25 MHz crystal oscillator and internal PLL provide a
50 MHz internal link-layer controller clock as well as
transmit/receive data at 100 Mbits/s, 200 Mbits/s, and
400 Mbits/s
— Interoperable across 1394 cable with 1394 physical
layers (PHY core) using 5 V supplies
— Provides node power-class information signaling for
system power management
— Supports ack-accelerated arbitration and fly-by
concatenation
— Supports arbitrated short bus reset to improve
utilization of the bus
— Fully supports suspend/resume
— Supports connection debounce
— Supports multispeed packet concatenation
— Supports PHY pinging and remote PHY access
packets
— Reports cable power fail interrupt when voltage at
CPS pin falls below 7.5 V
„ Link:
— Cycle master and isochronous resource manager
capable
— Supports 1394a-2000 acceleration features
„ PCI:
— Revision 2.2 compliant
— 33 MHz/32-bit operation
— Programmable burst size thresholds for PCI data
transfer
— Supports optimized memory read line, memory read
multiple, and memory write invalidate burst
commands
— Supports PCI Bus Power Management Interface
Specification v.1.1, including D3cold wakeups
— Supports CLKRUN# protocol per PCI Mobile Design
Guide
— Supports Mini PCI Specification v1.0, including Mini
PCI power requirements
— Global byte swap function
— CardBus support per PC Card Standard Release 8.0,
including 128 bytes of on-chip tuple memory.
