Product details
Overview
CY2292FXIT from Infineon Technologies (formerly Cypress Semiconductor) is a field-programmable, three-PLL clock generator in 16-pin SOIC package, supporting 3.3 V or 5 V operation. It delivers up to four low-skew clock outputs (CLKA–CLKD), CPUCLK with smooth slewing across eight selectable frequencies (up to 60 MHz at 3.3 V), and configurable power management via SHUTDOWN/OE and S2/SUSPEND pins. Used in PC motherboards and embedded control systems requiring flexible, multi-frequency timing.
For engineers reviewing the CY2292FXIT datasheet, CY2292FXIT pinout, CY2292FXIT application, or CY2292FXIT equivalent, key selection criteria include its EPROM-based field programmability, industrial temperature range (–40 °C to +85 °C), 76.923 kHz–60 MHz output capability at 3.3 V, tristate-enabled output control, and compatibility with CyClocks configuration software and FTG programmer.
Technical Context
The CY2292FXIT integrates three independent PLLs: CPLL for CPU clock generation with smooth frequency slewing across eight user-selectable rates; SPLL for fixed-frequency, high-division-ratio outputs on CLKA–CLKD; and UPLL for high-accuracy utility clocks. All PLLs accept a 10–25 MHz crystal or 1–30 MHz external reference clock.
Its EPROM-based configuration allows full factory or field programming of output frequencies, power modes, and input select logic (S0–S2). The device supports dual-voltage operation (3.3 V/5 V), shutdown current <50 µA, and output skew <500 ps between synchronized clocks - enabling precise timing in synchronous digital systems without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Frequency Range | 10–25 MHz crystal or 1–30 MHz external reference clock - enables direct use of standard crystals or system-level clock sources without conditioning. |
| Output Frequency Range (3.3 V) | 76.923 kHz–60.0 MHz - supports low-power embedded processors and peripherals requiring sub-100 MHz timing with tight jitter control. |
| Number of PLLs | Three independent PLLs (CPLL, SPLL, UPLL) - allows simultaneous generation of CPU, system, and auxiliary clocks from one reference source. |
| Output Skew | <500 ps between CLKA–CLKD - ensures deterministic setup/hold timing across multiple synchronous buses or memory interfaces. |
| Supply Current (3.3 V, typical) | 50–65 mA - scales with configured output frequencies; enables accurate power budgeting using provided formula. |
| Shutdown Current | <50 µA - reduces system standby power significantly while preserving configuration state in EPROM. |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial environments including motor control, networking, and ruggedized computing. |
Pinout & Package
Package: 16-pin Small Outline Integrated Circuit (SOIC), 300 mil width, RoHS-compliant, industrial-grade thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKA (10) | Configurable clock output A | One of four independently programmable outputs; assigned any of 30 frequencies via EPROM table. |
| CLKB (9) | Configurable clock output B | Low-skew companion to CLKA; shares same PLL source options and divider configurations. |
| CLKC (1) | Configurable clock output C | Supports same frequency set as CLKA/CLKB; used for secondary bus or peripheral timing. |
| CLKD (7) | Configurable clock output D | Final configurable output; may be derived from CPLL, SPLL, or UPLL depending on EPROM configuration. |
| CPUCLK (8) | CPU frequency clock output | Smooth-slewing output with eight selectable frequencies (e.g., 20–60 MHz); critical for dynamic voltage/frequency scaling (DVFS). |
| XTALIN (4) | Crystal/reference clock input | Accepts parallel-resonant crystal (10–25 MHz, CLOAD ≈ 17–18 pF) or AC-coupled external clock (1–30 MHz). |
| SHUTDOWN/OE (16) | Global output enable/shutdown control | Pull LOW to tristate all outputs and disable all active circuitry (PLLs, oscillator, counters); resumes operation after reassertion. |
| S2/SUSPEND (15) | CPU clock select bit 2 / suspend control | When configured as SUSPEND, disables selected PLLs/outputs without full shutdown - enables partial power gating. |
Key Features
| Feature | Design Value |
|---|---|
| Field-programmable EPROM | Enables post-manufacture frequency customization using Cypress FTG programmer and CyClocks software - eliminates NRE and long lead times. |
| Smooth CPUCLK slewing | Eight-step frequency transition (e.g., 20 → 33.3 → 40 → 50 → 60 MHz) without glitches - essential for green-mode processor throttling. |
| Low-output skew (<500 ps) | Guarantees matched propagation delay across CLKA–CLKD - removes need for external clock buffers in multi-sink applications. |
| Dual-voltage operation (3.3 V / 5 V) | Single part supports legacy 5 V and modern low-voltage designs - simplifies BOM consolidation and design reuse. |
| Configurable power management | Independent control of PLLs and outputs via SHUTDOWN/OE and S2/SUSPEND - enables hierarchical power states in complex systems. |

Equivalent & Alternatives
Two verified alternatives support similar multi-PLL, field-programmable clock generation with industrial temperature range and SOIC packaging.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT5V41001PGI | LVDS outputs, no slewing CPUCLK, fixed 3.3 V only, requires external EEPROM for configuration | Limited to high-speed serial interfaces; lacks dynamic frequency scaling for processors | Choose when LVDS signaling and deterministic startup timing outweigh slewing needs. |
| Si5338A-D-GM | Four PLLs, I²C programmable, integrated crystal option, higher max frequency (350 MHz), but larger 24-QFN package | Better suited for high-speed SerDes and JESD204B; not pin-compatible with SOIC footprint | Prefer for new designs needing >100 MHz outputs or crystal integration; avoid if SOIC layout reuse is mandatory. |
Compared with IDT5V41001PGI and Si5338A-D-GM, the CY2292FXIT uniquely combines SOIC pin compatibility, smooth CPUCLK slewing, EPROM field programming without external memory, and industrial temperature support - making it optimal for cost-sensitive, space-constrained upgrades of legacy motherboard and embedded control designs.

FAQ
What is the maximum output frequency supported by CY2292FXIT at 3.3 V operation?
The CY2292FXIT supports up to 60.0 MHz on CPUCLK and 66.6 MHz on other outputs (CLKA–CLKD) when operating at 3.3 V in industrial temperature grade. This limit is defined by electrical characterization under VDD = 3.0–3.6 V and TA = –40 °C to +85 °C, with guaranteed performance across the full range.
Can CY2292FXIT be programmed in-system without removing it from the PCB?
Yes - the CY2292FXIT is field-programmable via the Cypress FTG programmer (CY3670) and CY3095 adapter. Programming uses the SHUTDOWN/OE and S2/SUSPEND pins in conjunction with CyClocks software; no socket or de-soldering is required, enabling firmware-like clock configuration updates during production or field service.
Does CY2292FXIT require external passive components for crystal operation?
No external load capacitors are needed when using a parallel-resonant crystal with CLOAD ≈ 17–18 pF, as the internal oscillator circuit provides matching capacitance. For external reference clocks above 20 MHz, a 150 Ω pull-up resistor to VDD on XTALOUT is recommended per datasheet guidance - but no capacitors or resistors are mandatory for basic crystal operation.
How does the smooth slewing feature on CPUCLK work, and what are its timing constraints?
CPUCLK slewing transitions between eight pre-programmed frequencies (e.g., 20, 25, 33.3, 40, 50, 60 MHz) without glitches by dynamically adjusting the CPLL feedback divider while maintaining lock. Transition time is typically <100 µs, and the output remains within ±1% duty cycle deviation - enabling safe DVFS in ARM Cortex-A/M series processors without external sequencers.
