PCM Transcoder
The HC-5560 digital line transcoder provides encoding and
decoding of pseudo ternary line code substitution schemes.
Unlike other industry standard transcoders, the HC-5560
provides four worldwide compatible mode selectable code
substitution schemes, including HDB3 (High Density Bipolar
3), B6ZS, B8ZS (Bipolar with 6 or 8 Zero Substitution) and
AMI (Alternate Mark Inversion).
The HC-5560 is fabricated in CMOS and operates from a
single 5V supply. All inputs and outputs are TTL compatible.
Application Note #573, “The HC-5560 Digital Line
Transcoder,” by D.J. Donovan is available.
