Basically this is not a new idea and it ties the audio support into a chip not necessarily focused on audio. Such chips also tend to have less flexibility in support of the number of legacy audio interfaces. For simple audio needs, it is fine. For rapidly evolving audio requirements (such as speaker array support, DSP effects, noise suppression and echo cancellation, a flexible dedicated audio chip is better, IMO.

TDSCDMA is a standard developed in China and the only major market for it right now is China. It originally was a way to get around the Qualcom CDMA patents and licenses needed if China wanted to produce their own cell phone IP.

Could it be because of IP issues in other countries?

Ok, but why only in China if they are so good? This, I suspect is some low cost solution for low end smart phones.

It seems Dialog is winning both Apple and Samsung and this should bring them very good fortune.

Power Management along with Class-D amplifier is a very good idea so reduce the size of PCB, class D amplifier has become a necessity in all the phone due the requirement of speaker phone. This will also help in lowering the price in the competitive market.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
