ADF4001SP1BRU-RL7

Overview

The ADF4001SP1BRU-RL7 is a clock generator PLL from Analog Devices, part of the ADF4001 series. It features a 200 MHz bandwidth and operates on a 2.7 V to 5.5 V power supply. The device includes separate charge pump supply (VP) for extended tuning voltage in 5 V systems, programmable charge pump currents, and a 3-wire serial interface. Typical operating current is 4.5 mA with ultralow phase noise. It is housed in a 16-lead TSSOP package.

Feature Summary

• 200 MHz bandwidth with ultralow phase noise
• Separate charge pump supply (VP) allows extended tuning voltage in 5 V systems
• Programmable charge pump currents
• 3-wire serial interface

Applications

• Clock generation
• Low frequency PLLs
• Low jitter clock source
• Frequency translation

Procurement Notes

Verify the specific suffix 'SP1B' against official Analog Devices documentation to confirm pinout, temperature range, or packaging variations compared to standard ADF4001 variants. Ensure compatibility with existing board layouts when substituting.

Selection Notes

Select this component for applications requiring stable reference signals with low noise. Consider the 2.7 V to 5.5 V supply range and 4.5 mA typical current consumption. Verify that the 16-lead TSSOP package fits the design constraints.

Part Context

The ADF4001 series is designed for implementing clock sources for PLLs requiring very low noise, stable reference signals. It consists of a low noise digital PFD, precision charge pump, programmable reference divider, and programmable 13-bit N counter.

Replacement Considerations

Standard ADF4001 variants such as ADF4001BCPZ or ADF4001BRU may be functionally similar but differ in package (LFCSP vs TSSOP). Verify electrical specifications and pin compatibility before substitution.
