... AD13280 to approximately 0.8 V p-p differential. This helps prevent the large voltage swings of the clock from feeding through to the other portions of the AD13280 and limits the noise presented to the ENCODE inputs. A crystal clock oscillator can also be used to drive the RF transformer if an appropriate limited resistor (typically 100 Ω ...

... These switching currents are confined between ground and the DVCC pin. Standard TTL gates should be avoided because they can appreciably add to the dynamic switching currents of the AD13280. It should also be noted that extra capacitive loading increases output timing and invalidates timing specifications. Digital output timing is guaranteed with 10 pF loads ...
