MAX9383

The MAX9382/MAX9383 are high-speed PECL/ECL phase-frequency detectors designed for use in highbandwidth phase-locked loop (PLL) applications. The MAX9383 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 of MAX9383 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.
