20s with a 12GHz oscilloscope. Jitter measurements
are approximately proportional to the output period of
the device. Thus, a 10MHz device has approximately
twice the jitter value of a 20MHz device. The jitter per-
formance of all clock sources degrades in the pres-
ence of mechanical and electrical interference. The
MAX7384 is relatively immune to vibration, shock, and
EMI influences and thus provides a considerably more
robust clock source than crystal or ceramic resonator-
based oscillator circuits.
Initial Power-Up and Operation
An internal power-up reset asserts RST until the supply
voltage has risen above the power-on-reset threshold
(V
TH+
).
RST holds the microcontroller in a reset condition until
120μs after V
CC
has risen above V
TH+
. This reset delay
ensures that the clock output and the microcontroller’s
internal clock circuits have stabilized before the system
is allowed to start. Typical microcontroller reset delay
ranges from 1ms to 250ms to allow a slow crystal oscil-
lator circuit to start up. The MAX7384 has a fast startup,
eliminating the need for such a long reset delay.
Extended Temperature Operation
The MAX7384 was tested to +135
°
C during product char-
acterization and shown to function normally at this tem-
perature (see the
Typical Operating Characteristics
).
However, production test and qualification is only per-
formed from -40
°
C to +125
°
C at this time. Contact the fac-
tory if operation outside this range is required.
Power-Supply Considerations
The MAX7384 operates with a 2.7V and 5.5V power-
supply voltage. V
CC
provides power to the the internal
circuitry and V
L
supplies power to the clock and reset
outputs. Good power-supply decoupling is needed to
maintain the power-supply rejection performance of the
MAX7384. Bypass both V
CC
and V
L
to GND with a
0.1μF surface-mount ceramic capacitor. Mount the
bypassing capacitors as close to the device as possi-
ble. Use a larger value bypass capacitor if the MAX7384
is to operate with a large capacitive load. Use a bypass
capacitor value of at least 1000 times that of the output
load capacitance.
