Infineon Technologies CY22393ZXC-MZ2

Overview

CY22393ZXC-MZ2 from Cypress Semiconductor is a three-PLL, serial- and flash-programmable clock generator in 16-pin TSSOP package, supporting 8–30 MHz crystal input and delivering up to six CMOS clock outputs (CLKA–CLKC, CLKD, CLKE) with frequencies from 1 MHz to 200 MHz. It features ultra-wide programmable dividers (11-bit P, 8-bit Q, 7-bit post-divide), digital VCXO capability via on-die load capacitance tuning (6–30 pF in 0.375 pF steps), and power management including shutdown, OE, and suspend modes. Used in industrial embedded systems requiring multi-frequency clock synthesis with field reprogrammability.

For engineers reviewing the CY22393ZXC-MZ2 datasheet, CY22393ZXC-MZ2 pinout, CY22393ZXC-MZ2 application, or CY22393ZXC-MZ2 equivalent, key selection criteria include its triple-PLL architecture, flash-based nonvolatile configuration, 166 MHz reference clock support, glitch-free S2-controlled frequency switching, and compatibility with CyClocksRT™ software for in-system tuning.

Technical Context

The device integrates three independent PLLs-each with fully programmable 11-bit feedback (P) and 8-bit reference (Q) dividers-feeding a 4×4 crosspoint switch that routes signals to up to six output pins. PLL1 output feeds both the crosspoint and CLKE via a synchronous /2,/3,/4 post-divider; PLL2 and PLL3 feed only the crosspoint. All PLLs derive from a single crystal or external reference input (8–30 MHz).

Configuration is performed via two-wire serial interface (SDAT/SCLK) or through three LVTTL general-purpose inputs (S0/S1/S2), enabling eight frequency states with glitch-free transitions. Crystal drive strength and on-die linear load capacitors (6–30 pF, 0.375 pF step) are digitally adjustable, supporting precise VCXO operation and eliminating external capacitors.

FAQ

Is CY22393ZXC-MZ2 pin-compatible with CY22392?

Yes, CY22393ZXC-MZ2 is a functional upgrade to CY22392 with identical 16-pin TSSOP footprint and pin mapping. It retains backward compatibility for existing PCB layouts while adding flash programmability, enhanced PLL resolution, and digital VCXO capability not present in CY22392.

What is the maximum output frequency achievable on CLKA with CY22393ZXC-MZ2?

The maximum output frequency on CLKA is 200 MHz under commercial conditions and 166 MHz under industrial temperature range (–40°C to +85°C), as specified in Cypress's official selection guide for CY22393_I variants. This limit applies regardless of PLL configuration due to output buffer performance constraints.

Can CY22393ZXC-MZ2 operate with a 12.288 MHz crystal for audio clock synthesis?

Yes-12.288 MHz falls within the supported 8–30 MHz crystal range. Combined with its 11-bit P and 8-bit Q dividers, the device can generate standard audio rates (e.g., 48 kHz, 96 kHz, 192 kHz) with low jitter, and its digital VCXO feature allows fine-tuning to compensate for crystal tolerance or temperature drift.

Does CY22393ZXC-MZ2 require an external programmer for flash configuration?

Yes-initial flash programming requires Cypress's CY3672 programmer or compatible tool. However, once programmed, in-system updates can be performed via the two-wire serial interface (SDAT/SCLK) using CyClocksRT™ software without removing the device from the board.
