GL6551 Datasheet, PDF (1/5 Pages) Hynix Semiconductor – COMPANDER
Description
The GL6551 is a compander IC to expand
dynamic range at transmission/reception
systems and to improve the tone quality by
means of restricting noise. Two functions are
loaded on the IC, the one is the compressor
which has the 2/1 ratio of input/output ratio by
logarithm, and the expander which has the 1/w
ratio input/ output ratio by logarithm. The
GL6551equipped with input & filter Amp,
DATA IN OUT terminal. The GL6551 is well
suited for use in cellular radio MCA and handy
telephone set, radio communication systems.
