M5913 - COMBINED SINGLE CHIP PCM CODEC AND FILTER

General Description

The M5913 is fully integrated PCM (pulse code modulation) codecs and transmit/receive filter using CMOS silicon gate technology.

Key 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 maintain integrity of the PCM highway. On the transmit channel, digital outputs DX and TS X are held in a high impedance state for approximately four frames (500µs) after power up or.
