Colorado Springs, Colo. Designed for satellite applications, Aeroflex Colorado Springs, an Aeroflex Inc. company, says its radiation-hardened RadClock family of PLL-based clock generators is the first space-qualified solution that solves clock network design problems in aerospace applications with a single chip. The first products launched are the UT7R995 RadHard clock generator featuring eight-outputs and a UT7R9951 RadHard clock generator with dual-outputs.
Historically, clock networks are implemented with discrete devices along with special system design and layout methods due to a limited selection of space-qualified clock and frequency control solutions available to satellite systems designers, said the company. With the introduction of the new RAD clock devices, designers are now able to simplify their overall clock network design as well as lower the overall cost of the satellite subsystems.
The UT7R995 is a low-voltage, quad-bank, eight-output clock generator. Supporting a frequency range of 6 MHz to 200 MHz with less than 100 ps of cycle-to-cycle jitter, the new clock generator features output phase programmability for optimal timing control of high-performance microprocessor and communication systems, said the company. Also providing a 6 MHz to 200 MHz frequency range, the UT7R9951 is a low-voltage, single-bank, dual-output clock generator.
The RadClock products withstand total ionizing dose irradiation from 100K rads (Si) to 1M rads (Si). These devices are also latch-up immune to heavy ion energies in excess of 100 MeV-cm2/mg. The RadClock devices run from a 3.3-volt (V) core power supply while supporting independent 2.5-V or 3.3-V power supplies for each output bank. Both products will be available through a Standard Microcircuit Drawing (SMD) with QML Q and V qualification. Package options include a 48-lead ceramic flatpack and a 49-pin ceramic CGA.
The company said the adjustable phase feature ensures clock network timing integrity, which improves system reliability, as well as simplifies the design and layout of high performance systems. It also provides frequency multiplication and division options for each output clock bank.
The UT7R995 RadHard clock generator (QML Q) is priced at $1,500.00 each in quantities of 100. Prototypes are available in first quarter 2005 with production delivery in second quarter 20005.
