M5913 COMBINED SINGLE CHIP PCM CODEC AND FILTER

The M5913 is fully integrated PCM (pulse code modulation) codecs and transmit/receive filter using CMOS silicon gate technology. The primary applications for the M5913 are telephone systems : - Switching - M5913-Digital PBX’s and Central BLOCK DIAGRAM DIP 20 ORDERING NUMBER: M5913B1 Office Switchi.

M5913 Features

* The combo-chip can be powered up by pulsing FSX and/or FSR while a TTL high voltage is applied to PDN, provided that all clocks and supplies are connected. The M5913 has internal resets on power up (or when VBB or VCC are re-applied) in order to ensure validity of the digital outputs and thereby mai
