SAN DIEGO Applied Micro Circuits Corp. (AMCC) has unveiled what it describes as an off-the-shelf dual-channel serial backplane interconnect IC with boundary scan. The part is aimed at use in Gigabit Ethernet and Fibre Channel applications.
The S2002 scans I/O signals with IEEE 1149.1-compliant JTAG implementation. The part's integrated boundary scan is said to enhance customers' board-level test capabilities. Its internally series-terminated TTL outputs and internally biased LVPECL I/O also simplify board design and layout, according to AMCC.
The device has an operating range of 0.98 to 1.3 GHz, which suits it for serial backplane connectivity in Gigabit Ethernet, Fibre Channel and proprietary point-to-point links. Its two transceivers operate individually for a data capacity in excess of 2 Gbits/second.
Clock generation is performed by an on-chip transmit phase-locked loop that synthesizes a high-speed clock from a low-speed reference clock. On-chip dual receive PLLs synchronize directly to incoming signals while simultaneously retiming and regenerating the data stream.
The device supports differential PECL-compatible I/O for copper or fiber-optic component interfaces, for minimal crosstalk and maximum data integrity.
The S2002 dissipates 1.85 watts from a single 3.3-volt supply and comes in a 21 x 21-mm 156-pin TBGA. It's priced at $30 in 1,000-piece quantities.
