Detailed Description
The MAX9160 125MHz, 14-port LVTTL/LVCMOS clock
driver repeats the selected LVDS or LVTTL/LVCMOS
input on two output banks. Each bank consists of seven
LVTTL/LVCMOS series terminated outputs and a bank
enable. The LVDS input has a fail-safe function. The
MAX9160 has a propagation delay that can be adjusted
using an external resistor to set the bias current for an
internal delay cell. The LVTTL/LVCMOS outputs feature
200ps maximum output-to-output skew and ±100ps
maximum added peak-to-peak jitter.
The MAX9160 is designed to operate with a 3.3V sup-
ply voltage over the extended temperature range of
-40
°
C to +85
°
C. This device is available in 28-pin
exposed and nonexposed pad TSSOP and 32-lead
5mm x 5mm QFN packages.
Fail-Safe
A fail-safe circuit on the MAX9160 sets enabled outputs
high when the LVDS input is:
Open
Undriven and shorted
Undriven and terminated
Without a fail-safe circuit, when the LVDS input is
selected and undriven, noise may cause the enabled
outputs to switch. Open or undriven terminated input
conditions can occur when a cable is disconnected or
cut, or when a driver output is in high impedance. A
shorted input can occur because of a cable failure.
When the MAX9160 LVDS input is driven with a differ-
ential signal with a common-mode voltage between
IV
ID
/2I and 2.4V - IV
ID
/2I, the fail-safe circuit is not acti-
vated. If the input is open, undriven and shorted, or
undriven and parallel terminated, an internal resistor in
the fail-safe circuit pulls both of the LVDS inputs above
V
CC
- 0.3V, activating the fail-safe circuit and forcing
the output high (
