Crosspoint switch has 10ps jitter at 3.125Gbps

National Semiconductor Corp. says its DS25CP104 LVDS 4 x 4 crosspoint switch delivers the industry's best jitter performance (10ps typical) at data transmission rates of up to 3.125Gbps. The DS25CP104 is well suited for clock and data switching/routing in telecommunications, professional video, storage and ATE applications.

The DS25CP104 offers a feature set to enhance signal integrity in demanding applications such as XAUI (telecom) and SMPTE 424M (pro video). The product consumes 122mW per channel while boosting and equalizing FPGA or ASIC signals over cables and FR-4 backplanes. The device inputs have a wide common-mode voltage range that allows it to accept low-voltage positive emitter coupled logic (LVPECL), current-mode logic (CML) and LVDS signal levels without using coupling capacitors.

The system designer can configure the DS25CP104 with external pin control or a serial SMBus. The crosspoint also features 8kV ESD protection and 100 termination on the LVDS input and output pins to minimize insertion losses, component count and board space, said National.

National also is introducing the DS10CP154, a lower speed, lower power 4 x 4 crosspoint switch targeted at applications up to 1.5Gbps, and includes many of the same features as the DS25CP104.

The DS25CP104 (3.125Gbps) and lower power DS10CP154 (1.5Gbps), available now in 40-pin LLP packages, are priced at $8.75 and $4.75, respectively, each in quantities of 1,000.

National will demonstrate the DS25CP104 at the IBC in Amsterdam from September 7-11.
