The ML7224-001 is a VoIP codec that has speech codecs with four channels. These speech codecs support the PLC (Packet Loss Concealment) function, with the coding format selectable between G.711 (μ-law) and G.711 (A-law). The ML7224-001 is equipped with an echo canceller that supports a delay of 32 ms for each channel; it also has functions such as FSK generation, DTMF detection/generation, and tone detection/generation. The ML7224-001 is an LSI device best suited to add multichannel VoIP capability to a TA, router and others. Note that because this LSI device employs the method of downloading the DSP firmware from outside of the LSI to a built-in memory, it is capable of supporting functional expansion by changing the DSP firmware.
