Device Structure

Monolithic IC with integrated phase-locked loop (PLL), clock divider and multiplier capabilities. Uses an RF synth circuit in a single chip with all key functions for clock and frequency synthesis. All components on one chip inside a 20-lead LFCSP exposed pad package for good thermal performance.

Performance Characteristics

Handles frequencies up to 550MHz for high-speed RF applications. Accepts both CMOS and TTL input logic levels. Stable operation across industrial temperature range (-40°C~+85°C). Supports divider/multiplier functions to allow versatile output frequency generation. Low power consumption and stable output clock signals.

Application Environments

Used in wireless infrastructure, instrumentation, RF communication, and test & measurement equipment needing stable precise clock/frequency generation. Ideal for PLL-based frequency synthesis in transmitters, receivers, modems, and base stations. Reliable in industrial and commercial electronic systems operating within -40 to +85°C.

Selection Guidelines

Choose when an integrated RF PLL synthesizer is needed for frequencies up to 550MHz. Prefer for applications requiring high integration, small size, low power, and surface-mount design. Ensure supply options support 2.7V~5.5V range. Confirm compatibility with other CMOS/TTL logic devices.

Usage Considerations

Follow MSL 3 handling to avoid moisture damage in reflow processes (must mount within 168 hours of opening dry pack). Use correct supply voltage, and manage heat dissipation through exposed pad. Verify input logic levels match drive requirements. Review PCB layout for proper grounding and RF performance.

Potential Equivalent/Replacement Models
