Description
Integrated analog/digital device that^interfaces a UTOPIA L2 bus to a serial^backplane with optional 1:1 protection^using high speed Low Voltage^Differential Signal (LVDS) serial links.^
For framers or modems without^UTOPIA bus interfaces: optionally^provides cell delineation (I.432) across^16 clock and data (bit serial)^interfaces.^
Interworks with PM7351^S/UNI-VORTEX devices to implement^a point-to-multipoint serial backplane^architecture, with optional 1:1^protection of the common card.^
Interfaces to another S/UNI-DUPLEX^device (via a single LVDS link) to^create a simple point-to-point UTOPIA^bus extension capability.^
Interfaces to two S/UNI-DUPLEX^devices to create a 1:1 protected bus^extension.^
Requires no external memory devices.^
Low power 3.3V CMOS technology.^
Standard 5 pin P1149 JTAG port.^160 ball PBGA, 15mm x 15mm.^
In the LVDS receive direction: selects^traffic from the LVDS link marked^active and demultiplexes the individual^cell streams to the appropriate PHY^device.^
In the LVDS transmit direction: accepts^52-56 byte cell streams from up to 32^UTOPIA L2 compatible PHY devices,^multiplexing into a single cell stream^carried over two high speed LVDS^serial interfaces.^
Cell read/write to both LVDS links^available through the processor port.^Provides optional hardware assisted^CRC32 calculation across cells to^support an embedded inter-processor^communication channel acros^8/16 bit, 52 MHz extended UTOPIA L2^bus slave (compatible with PM7351^S/UNI-VORTEX).^
16 port, 4 pin clocked serial data^interface (Tx & Rx), with integrated^I.432 ATM cell delineation.
