Peregrine Semiconductor Corp. has unveiled the PE97632 3.2 GHz delta-sigma modulated fractional-N phase locked-loop (PLL) frequency synthesizer for low phase noise space applications such as high-capacity digital satellite payloads. It will address the growing demand for small form-factor IC solutions as satellite communications become more prevalent.

The PE97632 is a single-chip rad-hard PLL IC, allowing customers to meet their frequency synthesis requirements at a fraction of the cost, time and power consumption than any other solution on the market, claimed Peregrine. Today, rad-hard space applications needing this level of performance require that the function be developed by assembling up to 100 discrete components–-a solution that is difficult to engineer and manufacture and drives up weight and cost, Peregrine said.

Drop-in compatible with its predecessor, the PE9763, the PE97632 delivers a 4 dB to 10 dB improvement in close-in phase noise. The device features a normalized phase noise of -216 dBc/Hz, and, as a DSM fractional-N device, it offers complete frequency plan flexibility in a single chip. The improved performance delivered by PE97632, including increased capacity and transmission margin, translates directly into significantly higher value to the system operators.

The product is available in die or ceramic 68-lead CQFJ package and priced per customer specifications. Sampling to alpha-customers and S-level qualification has been completed.
