AD809BRZ

Overview

The AD809BRZ is an Integer-N frequency synthesizer manufactured by Analog Devices Inc., designed for precise clock generation applications. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 17 mA. The device accepts input frequencies between 9.72 MHz and 19.44 MHz and generates a fixed output frequency of 155.52 MHz. Constructed using Silicon technology, it functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 16-lead SOIC surface-mount package.

Feature Summary

• Integer-N PLL architecture for stable frequency synthesis
• Fixed output frequency of 155.52 MHz
• Input frequency range: 9.72 MHz to 19.44 MHz
• Single circuit configuration in SOIC-16 package

Applications

• Clock generation for digital communication systems
• Frequency synthesis in wireless infrastructure equipment
• Reference clock sources for data converters

Procurement Notes

Verify the specific suffix 'BRZ' against the official Analog Devices datasheet to confirm RoHS compliance and lead-free status. Confirm that the required output frequency of 155.52 MHz matches the fixed internal divider settings of this specific part number, as other variants may offer programmable outputs. Ensure the input clock source falls strictly within the 9.72 MHz to 19.44 MHz specification to guarantee proper lock acquisition.

Selection Notes

Select the AD809BRZ when a fixed 155.52 MHz clock is required from an input reference between 9.72 MHz and 19.44 MHz. This part is suitable for designs requiring a single PLL circuit with low power consumption (17 mA). Consider the SOIC-16 package dimensions for PCB layout constraints. Verify that the system environment remains within the -40°C to +85°C operating temperature range.
