Designed to meet Mil-Std-188-113 with external components, the device is suitable for applications in military Delta Multiplexers, switches and phones. Encoder input and decoder output filters are incorporated on-chip. Sampling clock rates can be programmed to 16, 32 or 64 k bits/second from an internal clock generator or may be externally applied in the range 8 to 64 k bits/ second. Sampling clock frequencies are output for the synchronization of external circuits. The encoder has an enable function for use in multiplexer appl……
