SAN JOSE -- Pericom Semiconductor Corp. here today announced a new product family from its SiliconClock division. The SuperClock family consists of 3.3- and 5-volt programmable skew, low jitter, phase-lock loop (PLL) clock buffers targeted at high-performance storage equipment, networking and telecommunications applications, such as the booming market for storage area networks (SAN).
The programmable skew clock buffer's speed is a whopping 125 MHz. The clock buffers also let designers minimize undesirable signal effects such as cross-talk and electromagnetic interference. Each output can be hardwired to one of nine delay or function configurations while the delay increments are determined by the input clock frequency and the configurations are selected by the user.
"The SuperClock gives designers a clock buffer solution that addresses today's most challenging board layout design problems in networking, telecom, and other applications," said Sergis Mushell, Pericom's SiliconClock product marketing engineer. Pericom's programmable skew clock buffers are the fastest in the industry and the easiest to program, he added.
Each clock buffer incorporates four pairs of programmable skew and zero propagation delay outputs that provide the timing delays to optimize high-performance clock distribution circuits. They provide user-selectable outputs that include multiply by two and four, divide by two and four, invert and non-inverted options. The clock buffers also enable the REF (Reference) clock input to perform spread spectrum modulation, that reduces EMI.
SuperClock's skew control is guaranteed to 250 picoseconds, with selectable skew between outputs from 750 ps to 18 nanoseconds.
The SuperClock family consists of four products, with several models consisting of 3.3- and/or 5-V parts and frequencies ranging from 3.75 up to 125 MHz. The SuperClock family is available in industrial and commercial operation temperatures.
Pericom is targeting markets that expect solid growth. According to Cahners In-Stat Group, growth in semiconductors for communications equipment is expected to average 23% for the next three years, growth for networking hardware is expected to be at 17% in 1999, and high-performance WAN gear is expected to grow 35% in 1999.
Pericom's SuperClock family is priced at $13.15 per 1,000 quantity.
