8 / 94 page  8 DS245F4 CS8420 DIGITAL INPUT CHARACTERISTICS DIGITAL INTERFACE SPECIFICATIONS AGND = DGND = 0 V; all voltages with respect to 0 V. TRANSMITTER CHARACTERISTICS SWITCHING CHARACTERISTICS Inputs: Logic 0 = 0 V, Logic 1 = VD+; CL = 20 pF. 5. Cycle-to-cycle jitter using 32-96 kHz external PLL components. 6. PLL is bypassed (RXD1:0 bits in the Clock Source Control register set to 10b), clock is input to the RMCK pin.
