The MAX9382/MAX9383 are high-speed PECL/ECL
phase-frequency detectors designed for use in high-
bandwidth phase-locked loop (PLL) applications. The
devices compare a single-ended reference (R) and a
VCO (V) input and produce pulse streams on differen-
tial up (U) and down (D) outputs. When integrated, the
difference of the output pulse streams provides a con-
trol voltage proportional to input phase or frequency dif-
ference. Guaranteed minimum short pulse duration
completely eliminates minimum phase difference
requirements during the lock condition, maximizing
loop jitter performance.
The MAX9382/MAX9383 feature low propagation and
reset delay, making them ideal for high-frequency clock
synchronization use. The MAX9382 uses 100K logic
levels, has a supply voltage range of V
to 5.5V, and is pin compatible with Motorola’s
MCK12140. The MAX9383 uses 10H logic levels with a
supply voltage range of V
is pin compatible with the MCH12140.
The MAX9382/MAX9383 are available in industry-stan-
dard 8-pin SO and space-saving 8-pin µMAX packages.
