19-2234; Rev 1; 11/02 ECL/PECL Phase-Frequency Detectors 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 propa...
