The DXS/C101 and DXS/C102 line interface solutions combine a CMOS codec and high-voltage SLICs in a single package. This reduced footprint provides the unrivaled flexibility and performance that is required to implement cost-optimized Voice CPE (Customer Premises Equipment) applications of superior design.
 
DXS/C complements MaxLinear´s established and field-proven Voice CPE product line and blends optimally with Home Gateways (DSL, PON, Cable, Ethernet) as well as small and medium sized Enterprise solutions. Its pin-to-pin compatible 1 and 2-channel solutions empower customers to produce a single hardware design implementing a 2-layer PCB. In comparison to the other devices that are available, DXS/C offers full transmission performance for Central Office (CO) compliance (for ringing, feeding, DTMF generation & detection, and Caller ID) over the entire industrial temperature range. DXS also supports industry standard (GR-909) line testing and unique tests such as Capacitance Measurement, AC Level Meter, Make-and Break Dial Tone and Universal Tone Detection.
 
The best-in-class Bill of Material (BOM) for dual-line termination is achieved through optimal on-board integration and elimination of duplicated external components, augmented by the device’s 2-layer PCB capability.
