MAX9383 Datasheet | Maxim Integrated

Description The MAX9382/MAX9383 are high-speed PECL/ECL phase-frequency detectors designed for use in highbandwidth phase-locked loop (PLL) applications. The devices pare 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 pletely 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 patible with Motorola’s MCK12140. The MAX9383 uses 10H logic levels with a supply...
