HC-5560, PCM Transcoder

PIN NUMBER 1 2, 5 FUNCTION Force AIS Mode Select 1, Mode Select 2 DESCRIPTION Pin 19 must be at logic ‘0’ to enable this pin.

A logic ‘1’ on this pin forces OUT1 and OUT2 to all ‘1’s.

A logic ‘0’ on this pin allows normal operation.

HC-5560 Data Sheet January 1997 File Number 2887.2 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
