description: | |
|
An i2c gate is useful to e.g. reduce the digital noise for RF tuners connected |
|
to the i2c bus. Gates are similar to arbitrators in that you need to perform |
|
some kind of operation to access the i2c bus past the arbitrator/gate, but |
|
there are no competing masters to consider for gates and therefore there is |
|
no arbitration happening for gates. |
