CXD1947Q
IEEE1394 LINK Layer / PCI Bridge LSI
Overview
The CXD1947Q is a single-chip implementation of the
link layer protocol of the 1394 Serial Bus, with additional
features to support the transaction and bus management
layers.
The CXD1947Q includes a PCI bus interface and mul-
tiple DMA engines to enable high performance bus
transfers.
