SCL220数据手册MaxLinear中文资料规格书

描述 Description

The SLC210 and SLC220 line interface solutions combine a CMOS ADC/DAC and DCDC control 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. SLC complements MaxLinear´s established and field-proven Voice CPE product line and blends optimally with MaxLinear’s Home Gateway platforms (DSL, PON, Cable). In comparison to the other devices that are available, SLC offers full transmission performance for Central Office (CO) compliance (for ringing, feeding, DTMF generation & detection, and Caller ID) over the entire industrial temperature range. SLC 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.
