Small Footprint, Cost Effective IC and Transformer Solutions for MIL-STD-1553 Applications

Friday, November 07, 2014

Mission Viejo, CA (November 7, 2014) - Holt Integrated Circuits supplies the smallest footprint solutions for MIL-STD-1553 applications available on the market today. All protocol ICs integrate dual analog transceivers on-chip and operate from a single 3.3V supply. Select products communicate with the host using a 4-wire Serial Peripheral Interface (SPI), further reducing pin-count and size. When paired with Holt’s MIL-STD-1553 transformers, the resulting combination results in a compact, highly robust solution.

The HI-6131, available in a 64-pin 9mm x 9mm QFN package, offers the smallest BC/MT/RT MIL-STD-1553 solution available. The HI-6121, available in the same package size, provides a more cost effective solution for customers requiring only an RT. Both devices have been in production for many years with a proven service history. They communicate with an external host using SPI and handle all aspects of the MIL-STD-1553 protocol, including message encoding, decoding, error detection, illegal command detection and data buffering. Host data management is simplified by storing message information and data within the on-chip 32K x 16-bit static RAM. The devices pair with the PM-DB2762, a dual core, dual ratio MIL-STD-1553 transformer (1:2.5 per channel). This transformer is available in a 0.4” x 0.52” (including leads) plastic package, resulting in a small footprint combination for the entire solution. In addition to the PM-DB2762, Holt offers an entire family of MIL-STD-1553 transformers with many ratios and industry standard package styles.

“The combination of our single chip, mixed signal ICs and highly compact magnetics provides our customers with a more reliable solution using fewer components,” said Anthony Murray, Director of Marketing Communications at Holt. “Holt continues to work towards lower SWaP and cost metrics, which are now becoming requirements of all military and aerospace manufacturers.”
