Overview
The ADF4001BCPZ is a 200 MHz clock generator PLL in a 20-lead LFCSP package. It integrates a low-noise digital phase frequency detector, precision charge pump, programmable reference divider, and 13-bit N counter with a 14-bit R counter. Operating on a 2.7 V to 5.5 V supply, it features a separate charge pump supply (VP) for extended tuning voltage. The device supports a 3-wire serial interface, hardware/software power-down modes, and analog/digital lock detect. Typical operating current is 4.5 mA, with ultralow phase noise characteristics suitable for stable reference signal generation.
Feature Summary
- 200 MHz bandwidth with 2.7 V to 5.5 V power supply range
- Separate charge pump supply (VP) allows extended tuning voltage in 5 V systems
- Programmable charge pump currents via CPI bits
- Hardware compatible with ADF4110/ADF4111/ADF4112/ADF4113
Applications
- Clock Generation
- Low Frequency PLLs
- SONET, ATM, ADM, DSLAM, SDM
Procurement Notes
Verify the B version suffix indicates an industrial temperature range of -40°C to +85°C. Confirm the LFCSP-20 package type matches design requirements. Ensure VP supply constraints (AVDD ≤ VP ≤ 6.0 V) are respected in system design. Check for ESD sensitivity precautions during handling.
Selection Notes
Select based on required output frequency stability and phase noise performance. The N counter minimum value of 1 provides flexibility in clock generation. Use external loop filter and VCO/VCXO to complete the PLL implementation. Consider the separate VP pin if tuning voltages exceed AVDD levels.
Part Context
The ADF4001BCPZ belongs to the ADF4001 family of clock generators. It is designed to implement clock sources for PLLs requiring very low noise and stable reference signals. The component serves as a core synthesizer element when paired with external passive components and oscillators.
Replacement Considerations
The datasheet notes hardware compatibility with the ADF4110, ADF4111, ADF4112, and ADF4113. Verify register map and pinout compatibility before substitution.
