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 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.
The MAX9382/MAX9383 are available in industry-standard 8-pin SO and space-saving 8-pin µMAX packages.

MAX9382EVKIT
Evaluation Kit for the MAX9382, MAX9383
Product Detail
The MAX9382 evaluation kit (EV kit) includes the MAX9382, a high-speed PECL/ECL phase-frequency detector. The EV kit evaluates the MAX9382, which compares single-ended reference (R) and VCO (V) inputs and produces pulse streams on differential up (U) and down (D) outputs, depending on the input phase or frequency difference. The EV kit operates up to 450MHz.
The MAX9382 EV kit is designed with 50Ω controlled-impedance traces in a four-layer PC board. The EV kit can also be used to evaluate the MAX9383.
Applications
- Automated Test Equipment (ATE)
- Central Office Telecom Equipment
- DLCs
- DSLAM
- Precision Clock Distribution
- Wireless Base Stations
