OPTICALLY COUPLED DIGITAL FILTER
Mii
OPTOELECTRONIC PRODUCTS
DIVISION
Features:
DSCC Approved 916761HXX
10 MBd typical
Meets Tempest EMI/RFI emanation criteria
TTL compatible input and output
RFI Rejection 80dB to 1GHz
Faraday shield to provide high common mode
rejection
Applications:
Military and space
Secure communication systems
Isolated receiver input
Microprocessor system interface
Digital isolation for A/D, D/A converters
DESCRIPTION
The 66079 Optically Coupled Digital Filter consists of an LED optically coupled to a high speed, high gain inverting detector
gate. Maximum isolation can be achieved while providing a TTL output capable of switching with propagation delays of 55nS
typical. The 66079 is a hermetically sealed package which is threaded in order to provide convenient bulkhead mounting and
is available in standard and screened versions or tested to customer specifications. The 66079-001 is a hermetically sealed
package which can be soldered or press-fit mounted and is also available in standard and MIL-PRF-38534 screened versions
or tested to customer specifications.
