DESCRIPTION
The LTDL-RA25A-T is a optical data link interface. The LTDL-RA25A-T
consists of an optical sensor with an
I / V amplifier, a Schmitt trigger, and a TTL output interface operating at data rates between 100K baud and 25
M baud.
FEATURES
* High PD sensitivty optimized for red light (λ=650nm)
* Data Rates between 100Kbps and 25 Mbps
* Low power consumption for extended battery life.
* Builit-in threshold control for improved noise margin
APPLICATIONS
* Digital Optical Data-Link
* Dolby AC-3 Digital Audio Interface
