Winbond Electronics Corporation America has introduced two families of ringing subscriber line interface circuits (RSLICs), the W671300 series and the W671500 series. These RSLICs are designed to work together with Winbond's existing A-Law/micron-Law CODEC portfolio of devices to terminate analog POTS lines. Together the CODEC/RSLIC chipset provides a solution supporting the complete BORSCHT feature requirements for short and medium loop length systems. This makes the chipset ideal for emerging customer premises equipment applications such as VoIP gateways, VoIP enabled DSL or cable modems as well as analog telephone adapters.
The RSLIC family can operate in both 5 V (W671500 Series) and 3,3 V (W671300 Series) environments. Each family supports several product grades offering customers the flexibility to match performance to individual system requirements. Each device, for example, supports on-chip ringing, ranging from 100 V in the high performance devices down to 75 V in the most cost-sensitive solutions.
Similarly, Winbond's voice CODEC portfolio offers a range of devices operating at 5 and 3 V in both single and dual channel architectures. Again, feature variation across the portfolio offers customers design flexibility. Both CODEC and RSLIC devices are distinguished by low power consumption, particularly in the power down and standby modes, which are the most critical in battery backup designs.
