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.
