SSM2125

The SSM2125 is designed as one kind of Dolby pro-logic surround decoders that is developed to provide multichannel outputs from dolby surround encoded stereo sources. This device is a premium grade that is selected to a minimum channel separation specification of 35 dB for the center to left and right channels, and 25 dB for the remaining channels. And this device is available only to licensees of dolby licensing corporation.

Features of the SSM2125 are:(1)noise generator and autobalance circuits are contained on-chip;(2)autobalance on/off control;(3)4-channel pro-logic and dilby 3 modes available;(4)selectable center channel modes - normal, wideband, phantom, off;(5)direct path bypass (normal 2-channel stereo mode);(6)wide channel separation center to left, right channels - 35 dB min;(7)wide dynamic range - 103 dB typ;(8)low total harmonic distortion - 0.02 % typ;(9)available in a 48-pin plastic DIP;(10)CMOS and TTL compatible control logic.
