CY22389FZXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY22389FZXC is a factory-programmable, quad PLL clock generator with an integrated analog VCXO. It operates at 3.3 V and supports output frequencies from 1 MHz to 166 MHz. The device features four independent PLLs capable of synthesizing unrelated frequencies from a single crystal or external reference (10–30 MHz crystal; 1–100 MHz external). It includes up to eight configurable clock outputs in a 20-pin TSSOP package. The analog VCXO provides a typical pull range of ±120 ppm for tracking external references.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component requires factory programming by Cypress Semiconductor. Standard ordering codes are not available for direct purchase; customers must contact a local Field Application Engineer (FAE) or sales representative to submit specific frequency and configuration requests. Upon processing, a unique part number is generated for samples and production orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY22389FZXC when a design requires multiple independent clock frequencies derived from a single reference source. Ensure the application utilizes a pullable crystal compatible with the specified load capacitance (12 pF nominal) and drive level (300 µW max). Verify that the required output count fits within the 20-pin TSSOP pinout constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY22389FZXC belongs to the CY22388 family, which also includes the CY22388 and CY22391 variants. These devices share the same core quad PLL and VCXO technology but differ in package options and output configurations. The CY22389 specifically utilizes a 20-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The datasheet states 'Replaced by: NONE'. No official replacement part numbers are documented for this obsolete component.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How does the VCXO function in this device?

The device uses an internal analog VCXO to 'pull' the reference crystal higher or lower, allowing the system frequency to lock to an external shifting reference source.
