Application Scenarios & Design Considerations

Quadrature Downconverter

Alternative Part Number

  • MT9172AP --: Mitel's telecom SLIC/line interface line was acquired by Microsemi (now Microchip); the MT9172 is a functionally similar subscriber line interface circuit in the same product family, making it a strong drop-in candidate after pinout verification.
  • LE58QL021 --: Zarlink inherited Mitel's telecom IC portfolio and the LE58 series SLICs are direct successors to the SL1711 family, offering comparable line interface functionality with similar supply and control interfaces.
  • HC55185 --: Intersil/Renesas SLIC devices such as the HC55185 provide equivalent subscriber line interface functions (battery feed, ringing, supervision) and are commonly used as second-source replacements for legacy Mitel SLIC parts.
  • MT9171AP --: Direct functional successor to the SL1711B ISDN subscriber line interface chip; Microchip acquired Zarlink and continues to support the same telecom line-card function with compatible pinout and specs.
