There's 2 bits per Hz, that is, the double-data-rate throughput. So a device specified as 110Mbps will have a bandwidth of about 55MHz. So this device should be adequate for your 20MHz single-data-rate application, but mind the inserted turn-around delay. 'Push-pull' operation only means that the driving device drives both high and low. This is typical of ...

For NRZ data is takes 2bits 01...01 to make 1Hz so 2MBps = 1MHz The ratio of pulse width is 30:1 is also the ratio of On R to OFF R pullup means push-pull with low R in each swing is what you need for > 1 MHz. To optimize this, the traces , cable ,should be matched to minimize reflections if the path length is > 10% of a wavelength at 2e8 m/s for a ...
