iSine has cost-effective and extremely efficient ballast IC drivers for both LED and CFL lighting. Lifetimes are dramatically increased because electrolytic capacitors are not neeeded.
iSine's standard products for lighting are detailed on the Lighting Industries page.
iSine has several intellectual property blocks, including a low-jitter (<10ps) PLL. We have developed many other core and I/O IP for a variety of technologies.
Low-Jitter Phase Lock Loop
This PLL Cell is designed for the TSMC 0.13µm process technology, but can also be used at 0.18µm. All loop filter components and dividers are fully integrated within the cell. A divide-by-N circuit is available to permit clock multiplication from a reference clock. A VCO post processing macro is available to produce VCO-half-rate and VCO-quarter-rate true and complement outputs. In addition, a four-phase (differential quadrature) direct VCO output clock is available. The VCO operates nominally at 280MHz, but is capable of operation from 140 to 500MHz. The cell achieves the frequency-multiply operations through the divider network shown in the PLL Cell Block Diagram below. Additionally, the feedback divide value is user selectable at each integer value between 4 and 16. For each valid M-divider value, recommended settings for two control bits are tabulated.

iSine's ACCEL™ Power Regulator can increase die yield, performance and reliability. This product will simplify time closure for both custom ICs and FPGAs. The ACCEL™ products were developed to control IC supply voltages, optimizing device performance. Better speed and power is achieved by optimizing for process, voltage, and temperature variations in real time.
By managing the supply voltage, ACCEL products optimize the speed-power point, negating the effects of fast and slow silicon process points and simplifying timing closure. ACCEL™ can also improve product lifetimes by as much as 400%!
The ACCEL™ product family is currently in use at the Dominion Radio Astrophysical Observatory's EVLA radio telescope in New Mexico. It has decreased power consumption and increased correlator lifetime.
