master time
Cypress Semiconductor has just announced the availability of production volumes of the CY22xxx family of field-programmable clock generators.
Cypress Semiconductor has just announced the availability of production volumes of the CY22xxx family of field-programmable clock generators Operating at speeds up to 200MHz, the timing devices provide highly stable, easily configurable clock outputs for use in a wide range of commercial and consumer applications, including switches, routers, computers, DVD players and digital cameras

Serial interface engine provides USB 2.0 for MCUs
Cypress Semiconductor has expanded its USB 2.0 product line with the introduction of the EZ-USB SX2 intelligent serial interface engine (SIE).
"These devices allow designers to use a simple software utility to create a customised clock solution, similar to the way they customise logic solutions for a CPLD", said Ian Chen, director of marketing for Cypress's Timing Technology Division.
"Instead of waiting months for a custom crystal or a custom PLL, designers can create a production-grade sample using an EPROM programmer in their labs in just 30min or less.
Furthermore, they can optimise a programmable clock for each application, guaranteeing peak performance.
At any volume the programmable device is as cheap or cheaper than a custom ASIC".
As companies push to create a greater variety of communications and connectivity applications and bring them to market in the shortest possible time, component engineers who can no longer qualify a large number of custom solutions are pushing to standardise product development around programmable clocks.
Manufacturers also benefit from easier inventory management.
Since these devices can be programmed with different personalities, excess inventory can be re-targeted for different applications instead of being sold for pennies on the dollar.
Cypress's new programmable clock family consists of the CY22392, CY22393, CY22394, CY22395 and CY22381.
All members feature a serial interface, low voltage outputs (2.5V), a digital VCXO feature, speeds up to 200MHz (400MHz with LVPECL), 30% lower period jitterand 70% lower long-term jitter than previous generation parts.
These clock generators are available now, configured with three phase-locked loops (PLLs) and packaged in an industry-standard, space-saving 16-pin TSSOP.
In volumes of 10,000, prices range from $1.90 for the CY22381 to $2.95 for the CY22395.
