The GSM Adaptive Multi-Rate Wideband (AMR WB) speech codec is used in the UMTS and CDMA2000 and 3GPP mobile telephony systems. The codec supports wideband speech with a 16kHz sampling frequency resulting in much higher speech quality.

"Developing the [USB] IP internally was never an option for us because it is not our core competency. Compared to other IP vendors we evaluated, Synopsys DesignWare USB 2.0 nanoPHY was 30% lower in area and up to 15% lower in power. It was one of the smallest PHYs we found. "
