Crosspoint Switch Raises Integrity Bar

Joining the company’s PowerWise family, two low-power, LVDS 2 x 2 crosspoint switches claim top honors in the signal-integrity department. The DS25CP102 delivers what may be the industry’s best jitter performance at 6 ps typical and at data rates to 3.125 Gb/s while consuming 125 mW of power per channel. The device features selectable transmit pre-emphasis and receive equalization to extend signal transmission reach in cables and FR-4 backplanes. Delivering data at rates to 1.5 Gb/s, the DS10CP152 addresses short-haul applications not requiring signal conditioning. It specifies a jitter performance of 9 ps typical with a power consumption of 57 mW per channel. Both devices perform as splitters or multiplexers for signal routing and switching in OC-48 telecom and standard- and high-definition SDI video applications. They are also suitable for video and imaging transport applications to select between two data streams or as a splitter to drive two monitors. Other features include 8 kV of ESD protection and 100-Ohm terminations on the LVDS input and output pins. Prices for the DS25CP102 in a 16-pin LLP and the DS10CP152 in a 16-pin narrow SOIC package are $5.25 and $3.65 each/1,000, respectively. NATIONAL SEMICONDUCTOR CORP., Santa Clara, CA.
