ECL/PECL Phase-Frequency Detectors

Active: In Production.

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 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 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-standard 8-pin SO and space-saving 8-pin µMAX packages.
