Preliminary
PM7390 S/UNI(R)-MACH48
* Provides a standard five signal IEEE 1149.1 JTAG test port for boundary scan board test purposes. * Provides a generic 16-bit microprocessor bus interface for configuration, control, and status monitoring. * Low power 1.8 V CMOS device with 3.3 V TTL compatible digital inputs and 3.3 V CMOS/TTL compatible digital outputs. * 560 pin Ultra BGA package.
Multi-Service Access Device for Channelized Interfaces
FEATURES
* Single chip ATM and packet processor capable of processing STS-48/STM-16 aggregate payload. * Optionally interprets the incoming AU-3/AU-4 pointers to locate payload frame boundaries. * Provides 48 ATM cell delineation blocks, 48 bit/byte HDLC processors, 48 DS-3 mappers, 48 DS-3 framers, and 48 PLCP framers. * Programmable assignments for allocating STS-1 timeslots to arbitrary DS3, STS-1/STM-0, STS-3c/STM-1, STS-12c/STM-4, or STS-48c/STM-16 channels. * Implements the ATM Forum User Network Interface Specification and the ATM physical layer for Broadband ISDN according to CCITT Recommendation I.432. * Implements the Point-to-Point Protocol (PPP) over SONET/SDH specification according to RFC 2615(1619)/1662 of * the PPP Working Group of the Internet Engineering Task Force (IETF). Supports a set of four duplex byteserial 77.76 Mbyte/s STS-12c/STM-44c line side parallel TelecomBus interfaces which can also be grouped into a single 32-bit-wide STS48c/STM-16c line side TelecomBus interface. Optionally supports two sets of four 777.6 Mbit/s LVDS serial TelecomBus links to transmit and receive working and protection 4xSTS-12/STM-4 or 1xSTS-48c/STM-16c line side data. Provides UTOPIA Level 3 32-bit wide System Interface (clocked up to 104 MHz) with parity support for ATM applications. Provides SATURN(R) POS-PHY Level 3TM 32-bit System Interface (clocked up to 104 MHz) for Packet over SONET/SDH (POS), HDLC, or ATM applications. Provides per-channel PRBS insertion and detection.
*
*
APPLICATIONS
