ECL/PECL Phase-Frequency Detectors
General Description
Features
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
