ECL/PECL Phase-Frequency Detectors
General Description
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
CC
- V
EE
= 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 V
CC
- V
EE
= 4.75V to 5.5V and
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.

*Ratings are for single-layer board.
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.

Note 1:
Measurements are made with the device in thermal equilibrium.
Note 2:
Current into a pin is defined as positive. Current out of a pin is defined as negative.
Note 3:
DC parameters are production tested at +85°C. DC limits are guaranteed by design and characterization over the full oper-
ating temperature range.
Note 4:
All pins open except V
CC
and V
EE
.
Note 5:
Guaranteed by design and characterization. Limits are set to ±6 sigma.
Note 6:
Phase offset is defined as the difference in propagation delay timing between the two input paths. It is measured between
the U and D outputs at the differential crosspoint with a rising edge simultaneously applied at the R and V inputs.
Note 7:
Device jitter added to the input signal.
