M
or EN1 low puts the corresponding driver output into a
high-impedance state (the differential output resistance
also becomes high impedance).
Applications Information
Unused Differential Inputs
Unused differential inputs should be tied to ground and
V
CC
to prevent the high-speed input stage from switch-
ing due to noise. IN_+ should be pulled to V
CC
with
10k
and IN_- should be pulled to GND with 10k
.
Expanding the Number
of LVDS Output Ports
Devices can be cascaded to make larger switches.
Total propagation delay and total jitter should be con-
sidered to determine the maximum allowable switch
size. Three MAX9152s are needed to make a 2 input x
4 output crosspoint switch with two device propagation
delays. Seven MAX9152s make a 2 input x 8 output
crosspoint with three device delays.
Accepting PECL Inputs
The inputs accept PECL signals with the use of an
attenuation circuit, as shown in Figure 9.
