​​​​​Teledyne HiRel Semiconductors Announces Radiation Tolerant Integer-N PLL for LEO Space Applications 

New product provides the Space RF engineering and design community with a non-hermetic off-the-shelf, Integer-N synthesizer for challenging high-reliability space applications. 

MILPITAS, CA – May 4th, 2023Teledyne HiRel Semiconductors, a leading provider of high-reliability semiconductor solutions, is proud to announce the release of a new space COTS (Commercial-Off-The-Shelf) phase locked loop (PLL) designed to deliver exceptional performance and reliability in space applications.  

The TDPL97240 is packaged in a small, 7x7 mm, non-hermetic, epoxy sealed, ceramic quad, no-leads, (QFN) flat package that offers 75% board size reduction vs. the standard space grade ceramic part. It is radiation tolerant to 100 krad (Si) total ionizing dose (TID) and built on silicon-on-sapphire (SOS) technology.  This gives the PLL natural radiation tolerance and immunity to single-event latch-up (SEL) effects.  It also has a lock frequency range of 50 MHz-5 GHz, dual modulus prescaler (5/6 & 10/11) for greater frequency flexibility and capability of either serial interface or direct pin programming.  

"We are thrilled to offer our customers a cost-effective solution that delivers the high-reliability and high-performance needed for space applications," said Mont Taylor, Vice President of Marketing and Product Management at Teledyne HiRel Semiconductors. "Our new space COTS PLL is the ideal solution for LEO applications that also require radiation performance." 

The device is qualified in accordance with the NASA EEE-INST-002 specification and undergoes rigorous testing and validation to ensure that it meets the necessary space requirements. The cost-effective nature of the space COTS solution opens new opportunities for customers who may have previously been unable to afford more expensive traditionally qualified solutions.
