CXD3204R
IEEE1394 LSI for D-STB, D-VHS, and DTV
Description
The CXD3204R is an LSI integrating Link Layer and
Physical Layer conforming to the IEEE1394-1995 serial
bus standard on a single chip.
Link Layer provides MPEG2 t ra nsp or t stre am
dedicated input interface and output interface, IEC958
audio stream I/O interface and output interface for D/A
c o nve r t e r a s a d a t a i n t e r fa c e fo i s o c h r o n o u s
communication. Also, a maximum 512 bytes of
asynchronous communication is possible.
Physical Layer provides two poarts for 1394 cable
i n t e r fa c e , a n d s u p p o r t s t r a n s fe r s p e e d o f
200/100Mbit/s. Also, this layer provides received packet
data regeneration repeat function, arbitration function
and bus initialization logic.
