Exar has expanded its communications portfolio by entering the market for clock distribution devices. The company unveiled a family of five new programmable skew clock components - including an industry first: smallest package (32-pin) and the highest frequency range (200 MHz) of any 3,3 or 2,5 V devices.
Whether regulating data transmissions or executing system instructions, clocks perform the critical role of producing precisely timed and repeated impulses that synchronise the overall system or other embedded applications. Driving the need for better performing clocks are faster processors, faster memory and increasingly lower voltage requirements, especially in new designs. Keeping pace with these trends has put new demands on clocks for lower jitter, better skew specifications and device reliability. Exar, with a long history of analog and phase lock loop design expertise, developed the XRK499x series of innovative clock and timing devices targeting wireless basestations, network switches and routers, among others.
In addition to the other four new programmable skew clocks, the XRK4999 is an industry-first. Three elements distinguish the component from competitive offerings: a 32-pin package for either 3,3 or 2,5 V, a redundant input clock and the widest frequency range (3,75 to 200 MHz) with a four-bank skew and 250 picosecond accuracy. Exar is the only company to offer these in a single solution, which is critical in designing highly integrated, small form factor components for leading edge networking and transmission applications.
