FEATURES
• Monolithic Saturn Network Interface that implements the ATM physical layer
   for Broadband ISDN according to the ATM Forum User Network Interface
   Specification and CCITT Recommendation I.432.
• Operates at 155.52 MHz in conjunction with an external clock and data
   recovery device. Provides on-chip parallel to serial and serial to parallel
   circuits with pseudo ECL interfaces to process a duplex 155.52 Mbit/s STS-
   3c/STM-1 data stream.
• Supports a 19.44 Mbyte/s line interface option for devices requiring a byteserial STS-3c/STM-1 interface.
• Provides 4 cell deep FIFO buffers in both transmit and receive paths with a
   byte-wide or word-wide system side datapath interface.
• Provides a generic 8-bit microprocessor bus interface for configuration,
   control, and status monitoring.
• Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board
   test purposes.
• Low power, +5 Volt, CMOS technology.
• 160 pin high performance plastic quad flat pack (PQFP) package.
