Avago Technologies has announced the 10 MBd HFBR-3810Z Fiber Optic (FO) short link transmitter/receiver for isolating frequency inverter and power converter applications common in renewable energy installations.
The FO short link technology pin-to-pin distance of 24.96mm provides transient voltage suppression of 12kV according to IEC 60664-1. Avago’s FO short link technology allows galvanic isolation on one PCB where previously separate transmitter/receiver pairs on two PCBs were linked by plastic optical fibre for isolation. FO short link devices have creepage and clearance specifications greater than existing optocoupler devices and offer superior galvanic isolation than transformer-based technology. The Avago HFBR-3810Z short link transmitter/receiver operates reliably in high noise environments common in high-voltage switching and motor control equipment and systems. The DC coupled data link does not require data encoding or digitising circuitry. The FO receiver has a CMOS/TTL output for easy interface design.
