FS6131-01/FS6131-01g Programmable Line Lock Clock Generator IC
However, the full signal amplitude may take up to twice as long as the propagation delay of the line to develop, reducing noise immunity
during the half-amplitude period. Note that the voltage at the receive end must add up to a signal amplitude that meets the receiver
switching thresholds. The slew rate of the signal may be reduced due to the additional RC delay of the load capacitance and the line
impedance. Also, note that the output driver impedance will vary slightly with the output logic state (high or low).
11.3 Serial Communications
Connection of devices to a standard-mode implementation of the I
resistors (R
the number of connected devices with their associated input currents.
Control of the clock and data lines is done through open drain/collector current-sink outputs, and thus requires external pull-up resistors
on both lines.
A guideline is
where t
other devices on the bus, including this one, results in values in the 5kW to 7kW range. Use of a series resistor to provide protection
against high voltage spikes on the bus will alter the values for R
