Product details
Overview
CY2292FXCT from Infineon Technologies (formerly Cypress Semiconductor) is a three-PLL, EPROM-programmable clock generator in 16-pin SOIC package, supporting 3.3 V or 5 V operation, with field-programmable configuration, eight CPUCLK slewing frequencies up to 66.6 MHz (3.3 V), and low-jitter outputs for PC motherboard timing systems.
For engineers reviewing the CY2292FXCT datasheet, CY2292FXCT pinout, CY2292FXCT application, or CY2292FXCT equivalent, key selection criteria include its field-programmable EPROM architecture, S0–S2-controlled CPUCLK slewing, tristate/shutdown power management, and compatibility with ICD2023/ICD2028-based legacy designs.
Technical Context
The CY2292FXCT integrates three independent PLLs: CPLL for smooth-slewing CPUCLK (8 selectable frequencies), SPLL for high-divisibility system clocks, and UPLL for highest-accuracy utility outputs. All PLLs accept a 10–25 MHz crystal or 1–30 MHz external reference clock.
Its EPROM-based configuration enables one-time field programming via Cypress FTG programmer (CY3670 + CY3095 adapter). Output skew between CLKA–CLKD is under 500 ps, and all four configurable outputs support independent frequency assignment from 76.923 kHz to 66.6 MHz at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Frequency Range | 10–25 MHz crystal or 1–30 MHz external reference clock - supports standard XTALs and buffered clock sources without external load components. |
| Output Frequency Range (3.3 V) | 76.923 kHz–66.6 MHz - covers DDR, PCI, USB, and legacy bus timing requirements in low-voltage embedded systems. |
| CPUCLK Slewing Options | 8 user-selectable frequencies with smooth transition - enables dynamic power scaling in green computing applications without clock glitches. |
| Supply Voltage | 3.0–3.6 V or 4.5–5.5 V - dual-voltage operation allows drop-in replacement across 3.3 V and 5 V legacy platforms. |
| Output Skew (CLKA–CLKD) | <500 ps - ensures synchronous signal integrity across multiple bus domains on dense motherboards. |
| Shutdown Current | <50 µA (commercial temp) - enables ultra-low-power suspend states while retaining EPROM configuration. |
| Package | 16-pin SOIC - industry-standard footprint compatible with automated PCB assembly and thermal management. |
Pinout & Package
Package: 16-pin Small Outline Integrated Circuit (SOIC), 300 mil width, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKC (Pin 1) | Configurable clock output C | One of four independently programmable outputs; assigned any supported frequency via EPROM table. |
| VDD (Pins 2, 14) | Power supply | Dual-rail capable: accepts 3.3 V or 5 V; decoupling required per datasheet layout guidelines. |
| GND (Pins 3, 11) | Ground reference | Dedicated analog/digital ground pins reduce noise coupling between PLLs and outputs. |
| XTALIN (Pin 4) | Crystal/reference clock input | Accepts parallel-resonant crystal (10–25 MHz) or AC-coupled external clock (1–30 MHz). |
| XTALOUT (Pin 5) | Crystal feedback output | Drives crystal; must be floated when using external reference clock instead of crystal. |
| XBUF (Pin 6) | Buffered reference clock output | Provides clean, low-skew copy of XTALIN for downstream clock distribution or monitoring. |
| CLKD (Pin 7) | Configurable clock output D | Fourth programmable output; shares skew performance and divider flexibility with CLKA–CLKC. |
| CPUCLK (Pin 8) | Primary CPU clock output | Smooth-slewing output controlled by S0–S2; maximum 66.6 MHz at 3.3 V for CY2292FXCT. |
| SHUTDOWN/OE (Pin 16) | Global control input | Active-low tristate + shutdown; pulls all outputs low when tristated due to internal weak pull-downs. |
Key Features
| Feature | Design Value |
|---|---|
| Three dedicated PLLs (CPLL/SPLL/UPLL) | Enables simultaneous generation of CPU, system, and utility clocks with independent stability and jitter profiles. |
| Field-programmable EPROM | Allows post-manufacture customization using Cypress FTG programmer (CY3670 + CY3095), eliminating NRE and long lead times. |
| S0–S2 CPU clock select interface | Hardware-selectable 8-frequency slewing without software intervention - critical for real-time power management. |
| Low-skew multi-output architecture | Sub-500 ps skew across CLKA–CLKD ensures timing margin compliance in high-speed parallel buses (e.g., PCI, LPC). |
| Configurable 3.3 V / 5 V operation | Single BOM item supports mixed-voltage board designs and legacy 5 V upgrades without redesign. |

Equivalent & Alternatives
CY2292FXCT has two verified alternatives with documented functional trade-offs for design continuity and sourcing resilience.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY2292F | Same die, identical pinout and EPROM architecture; differs only in ordering suffix (no temperature grade or package variant encoded). | No functional difference; CY2292F is base part number - CY2292FXCT denotes commercial-temp, SOIC, tape-and-reel packaging. | Select CY2292F for prototype evaluation or non-tape-and-reel procurement; CY2292FXCT for production volume with standardized packaging. |
| ICS952002AGLFT | Fixed-function, non-programmable clock generator with 4 outputs; lacks EPROM, slewing, and suspend features; higher typical jitter (>150 ps RMS). | Suitable only for static clock trees where frequency changes are unnecessary; not viable for CPU slewing or field customization. | Choose only if design requires zero-programming logistics and fixed 100/133/166 MHz outputs - otherwise CY2292FXCT offers superior flexibility and power control. |
Compared with CY2292F (identical functionality, packaging-neutral) and ICS952002AGLFT (fixed-function, no slewing or programming), CY2292FXCT uniquely delivers field-programmable frequency agility, hardware-controlled CPUCLK slewing, and sub-500 ps skew - making it irreplaceable for adaptive timing architectures requiring both precision and configurability.

FAQ
Is CY2292FXCT factory-programmed or field-programmable?
CY2292FXCT is field-programmable using the Cypress FTG programmer (CY3670) with CY3095 adapter. Unlike factory-programmed variants (e.g., CY2292SC), it retains blank EPROM until configured via CyClocks software and programmed in-system or at the bench - enabling rapid iteration and late-stage frequency tuning.
What is the maximum output frequency at 3.3 V operation?
At 3.3 V, CY2292FXCT supports up to 66.6 MHz on CPUCLK (for commercial temperature grade) and up to 60.0 MHz for industrial-grade variants. This limit is defined by internal PLL voltage scaling and is confirmed in the "Selector Guide" section of datasheet 38-07449 Rev. *M.
Does CY2292FXCT require external passive components for crystal operation?
No external capacitors or resistors are required for crystal operation. The internal oscillator is optimized for parallel-resonant crystals with ~17–18 pF load capacitance. When using an external reference clock instead of a crystal, XTALOUT must be floated and no load components are needed.
How does the SHUTDOWN/OE pin behave in tristate mode?
When SHUTDOWN/OE is pulled LOW, all outputs enter tristate and are actively pulled low via internal weak pull-downs (not floating). If shutdown mode is enabled, PLLs, counters, and the reference oscillator also power down, reducing VDD current to under 50 µA - verified in the "Power Saving Features" section of the datasheet.
