National Semiconductor Corp. has introduced the DS90CP04, which the company claims to be the industry's first LVDS-compliant 4x4 crosspoint switch. The 6-by-6mm device is also claimed to consume 575mW at 2.5Gbpshalf the power of competing switches in the market.

For long haul and metro communications applications, the switch can be used as a versatile switch-fabric solution for both simple and complex configurations. In serial digital interfaces used in the broadcast video industry, the DSP90CP04 can accommodate data rates for systems that include 270Mbps and 360Mbps for standard definition, and 1.5Gbps for HDTV.

The DS90CP04 can also be used for protection switching for Gigabit Ethernet serial streams through a backplane, as well as to concentrate several data and voice streams into one high-speed link in tributary cards of multi-access controllers.

The switch's LVDS I/O accepts LVPECL, CML, or LVDS inputs and provides CML or LVDS outputs. Data paths of the DS90CP04 are fully differential from input to output to minimize EMI. It also has a non-blocking architecture to allow connections of any input to any output.

The device's switch matrix consists of four differential 4:1 MUXs with each output channel connecting to one of the four inputs common to all MUX. The output channel is capable of operating at 2.5Gbps and even up to 3.125Gbps depending on loading and required signal integrity.

The DS90CP04 is manufactured using a CMOS process and is shipped in an LLP-32 package.
