The data rate of the sinc filter (filter throughput) represented in samples/sec is calculated by the following formula:
The latency of the sinc filter represented in secs is defined as the amount of time taken by a sinc filter type to deliver the correct filtered output upon initiation. For a given filter type, latency is calculated by the following formula:
Example configuration:
| Sinc filter type | = sinc3 |
| Modulator data rate | = 10 MHz |
| OSR | = 256 |
| Data rate of Sinc Filter | = 10 MHz / 256 = 39.1 K samples / sec |
| Sinc filter latency | = 76.8 µs |
| Sinc filter type | = sinc2 |
| Modulator data rate | = 10 MHz |
| OSR | = 256 |
| Data rate of Sinc Filter | = 10 MHz / 256 = 39.1 K samples / sec |
| Sinc filter latency | =51.2 µs |
