This document is the user manual for the CY22395, CY22393, CY22394 three clock generators from Cypress Semiconductor Corporation. The document introduces the features and characteristics of the products, including the common features of the three products, as well as the different features of the three products.
This manual describes the three‑PLL serial‑programmable flash‑programmable clock generator family (CY22393, CY22394, CY22395). It lists the integrated PLLs, ultra‑wide divide counters, crystal load options, power‑management features, and optional I2C serial interface for in‑system configuration.
The document also covers pin definitions, programming procedures, power‑saving modes, jitter optimization, and the CyClocksRT software used to calculate PLL settings and estimate power consumption.
| Number of outputs | 6 |
|---|---|
| Input frequency range (external crystal) | 8 MHz–30 MHz |
| Maximum output frequency (commercial temperature) | 200 MHz |
They can be programmed via the I2C two‑wire serial interface or with an external programmer using flash programming.
