Pericom Semiconductor Corp. announced the initial release of its SaRonix S1643 and S1644 product series of quartz crystal clock oscillators contained in a 3.2-by-2.5mm package. According to the press release, this ceramic package is 75 percent smaller than the popular 7-by- 5mm clock oscillator package. This reduced package size facilitates the size-reduction of customers' platforms or the addition of more features/functions to existing platforms, said Pericom.

The S1643 and S1644 feature operating frequencies from 1.8432MHz to 106.25MHz with 3.3V and 2.5V LVCMOS interfaces suited for use in small form-factor hard disk drives, GPS devices, portable multimedia players or recorders, digital cameras, blade servers, switches and routers, portable and personal computing devices, wireless access devices, and PON and SOHO networking equipment.

Powered with 3.3V or 2.5V supply, the two clock oscillators use a non-PLL clock circuit to achieve low output jitter and low current consumption, rated 8mA max (up to 50MHz) and 15mA max (up to 106.25MHz), suited for battery-operated or high-density PCB applications requiring low power dissipation. The products also achieve 25ppM total accuracy over commercial operating conditions and 50ppM total accuracy over industrial operating conditions.

The S1643/44 products are available for initial samples and prototype requirements. Common operating frequencies include 1.8432-, 3.0720-, 3.6864-, 10-, 20-, 24-, 25-, 27-, 40-, 48-, 50-, 75-, 100- and 106.25MHz. Prices start around $1.10 each for 1,000 pieces. The devices are available on tape and reel for automated pick-and-place assembly, and are RoHS-compliant and compatible with Pb-free reflow soldering guidelines.
