Control Functions
The MAX3772
–
MAX3775 have two control inputs:
RATESEL and CLKEN.
RATESEL is an input that sets the operational data rate
for the repeaters. Table 1 shows the selected input
data rates when using the RATESEL function.
CLKEN is an input that can be used to enable or dis-
able the output clock, as shown in Table 2.
Layout Procedure
The MAX3772
–
MAX3775 performance can be greatly
affected by circuit-board layout and design. Use good
high-frequency design techniques, including minimiz-
ing ground inductance and using fixed-impedance
transmission lines on the data and clock signals. All IN,
OUT, and CLK pins should be connected with 0.1μF
coupling capacitors equivalent or better than X5R.
A 0.047μF capacitor should be used for the loop filter. If
DC coupling is desired pay particular attention to the
DC voltage and current requirements at the pins of
interest (see
DC Electrical Characteristics
). The
MAX3750/MAX3754/MAX3755 port bypass circuits can
be DC-coupled to the Maxim dual-rate repeaters. The
exposed paddle of the repeater must be connected to
ground and should be soldered onto the circuit board
for optimal thermal and electrical operation.
