CXD1948R

CXD1948R IEEE1394 Link Layer LSI for DVB and DSS For the availability of this product, please contact the sales office. Description The CXD1948R is a Link Layer LSI conforming to the IEEE1394 serial bus standard. During transmission, the MPEG2 transport stream is time stamped, transformed to IEEE1394 format and sent to the IEEE1394 Phy IC. During reception, the signal from IEEE1394 is kept in the built-in FIFO, synchronized to the time stamp value and output. This IC utilizes Apple Computer’s Fire Wire technology. Features Conforms to IEEE1394 serial bus standard Supports DVB and DSS transport streams Dedicated ports for asynchronous data/isochronous data Isochronous data inserted from asynchronous data port Smoothing buffer function Large capacity FIFO Isochronous transmit/receive FIFO 960 × 32 bits Asynchronous transmit FIFO 30 × 33 bits Asynchronous receive FIFO 36 × 33 bits Isochronous Insert Packet Transmit Buffer 47 × 33 bits CIP header automatic attachment/detection Applications Digital interface for D-STB Digital interface for D-VHS Structure Silicon gate CMOS IC 100 pin LQFP (Plastic) Absolute Maximum Ratings (Ta = 25°C) Vss – 0.5 to +4.6 Supply voltage VDD Input voltage VI Vss – 0.5 to VDD + 0.5 Output voltage VO Vss – 0.5 to VDD + 0.5 Operating temperature Topr –20 to +75 Storage temperature Tstg –55 to +150 Recommended Operating Conditions Supply voltage VDD 3.0 to 3.6 Operating temperature Topr –20 to +75 V V V °C °C V °C Fire ...
