MAXIM MAX9382, MAX9383 Technical data
General Description
The MAX9382/MAX9383 are high-speed PECL/ECL
phase-frequency detectors designed for use in highbandwidth phase-locked loop (PLL) applications. The
devices compare a single-ended reference (R) and a
VCO (V) input and produce pulse streams on differential up (U) and down (D) outputs. When integrated, the
difference of the output pulse streams provides a control voltage proportional to input phase or frequency difference. 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 VCC- VEE= 4.2V
to 5.5V, and is pin compatible with Motorola’s
MCK12140. The MAX9383 uses 10H logic levels with a
supply voltage range of VCC- VEE= 4.75V to 5.5V and
is pin compatible with the MCH12140.
The MAX9382/MAX9383 are available in industry-standard 8-pin SO and space-saving 8-pin µMAX packages.

ABSOLUTE MAXIMUM RATINGS
MAX9382 DC ELECTRICAL CHARACTERISTICS
(VCC- VEE= 4.2V to 5.5V. Outputs loaded with 50Ω ±1% to VCC- 2V, unless otherwise noted. Typical values at VCC- VEE= 4.5V.)
(Notes 1, 2, 3)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
