Right. Also the above linked Audio Sample Rate Converter block diagram uses it. It's obviously providing asynchronous rate conversion, e.g. 44.1 to 192 kHz. It's part of the AES3/EBU Reference Design, that can be obtained from Altera. Also a reference design for the AN347 farrow rate converter is available.

The asynchronous sample rate converter converts stereo audio from one sample frequency to another. The input and output sample frequencies may be an arbitrary fraction of one, or another or the same frequency but based on different clocks. The output is a band-limited version of the input, re-sampled to match the output sample timing.

32 kHz: 48 kHz up-conversion: Latency = 32 + 16 = 48 input sample periods = 1.5 ms. Latency Example 4. 96 kHz: 48 kHz down-conversion: Latency = 32 • 2 + 16 = 80 input sample periods = 0.83 ms. Latency Example 5. 48 kHz: 44.1 kHz down-conversion: Latency = 32 † 48/44.1 + 16 = 50.83 input samples = 1.06 ms.
