The encoder has an enable function for use in

multiplexer applications.

Encoder and Decoder forced idle facilities are

provided, forcing a 10101010..... pattern in

encode and a V

DD/2 bias in decode.

The companding circuits may be operated with

a pin-selected 3 or 4-bit algorithm.

The powersave facility puts the device into the

standby mode thereby reducing current

consumption when not operating.

A reference 1.024MHz oscillator uses an

external clock pulse or Xtal input.

The FX629 is a low-power, 5 volt CMOS

device and is available in 22-pin cerdip DIL

package.

Forced Idle Facility

The FX629 is an LSI circuit designed as a

*Continuously Variable Slope Delta Codec and

is intended for use in military communications

systems.

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.
