B2-AMC Card

Quad ADSP-TS201 TigerSHARC Universal Baseband Processing Module

Universal Baseband Processing:

• 2G, 2.5G and 3G wireless standards
• WiMAX PHY
• Software Defined Radio (SDR)

Programmable Baseband Processing for Wireless Communications Infrastructure

Featuring the Analog Devices ADSP-TS201S TigerSHARC processor, BittWare's B2-AMC (B2AM) is an Advanced Mezzanine Card (AMC) that supports universal baseband processing for wireless communications infrastructure such as 2G, 2.5G, 3G, WiMAX and SDR. A full-height, single wide AMC, the B2AM attaches to AdvancedTCA (Advanced Telecom Compute Architecture) carriers or other cards equipped with AMC bays and is completely hot-swappable.

The B2AM features four TigerSHARCs, an Altera Stratix II FPGA, a variety of front and back panel I/O interfaces and a configurable 4x network interface supporting a variety of protocols. It also provides a 10/100 Ethernet interface and a Gigabit Ethernet interface for command, control, and reprogramming, as well as Flash memory for booting the DSPs and FPGAs.

The BittWare B2AM features a single cluster of four ADSP-TS201S TigerSHARC DSPs from Analog Devices, providing a total of 14.4 GFLOPS of floating point processing power and 57.5 GOPS of 16-bit fixed point processing power. In addition to 24 Mbits of on-chip RAM, each TigerSHARC also boasts four high-speed LVDS link ports.

Each full-duplex link port is comprised of a 4-bit transmit and a 4-bit receive channel, and can support up to 500 MBytes/s in each direction for a total maximum throughput of 1 GByte/s. Two link ports from each DSP are used to create an interprocessor communications ring and the remaining two link ports are routed to the on-board FPGA.

Fat Pipes, Common Options and I/O Interfaces

An Altera Stratix II FPGA facilitates off-board I/O and provides communications routing and processing. It implements eight TigerSHARC DSP link ports and supports a variety of external I/O, flags and interrupts. Efficient routing is achieved using BittWare's ATLANTiS architecture, which tightly integrates the DSPs with the I/O peripherals and the FPGA and allows any combination of link ports and off-board I/O interfaces to be routed together, providing nearly infinite options for configuring the I/O.

The Altera Stratix II interfaces to four ports in the AMC fat pipes via PMC Sierra's QuadPHY SerDes. The four ports provide a network data and control switch fabric interface on the AMC connector, configurable to support PCI Express, Advanced Switching Interconnect (ASI), Serial RapidIO, GigE, or XAUI. Alternatively, a single SerDes port can be run via a front panel fiber transceiver.

BittWare's SharcFINe Bridge provides Gigabit Ethernet via the common options region or can be optionally configured for PCI Express. It also provides 10/100 Ethernet and RS- 232 on the AMC front panel.

The Stratix II provides 11 pairs of LVDS I/O (5 Rx, 1 Rx clk, 5 Tx) for proprietary antenna or network interfaces and 24 bits of general purpose digital I/O available on the AMC front panel.
