Product details
Overview
CY24293ZXCT from Infineon Technologies is a programmable clock generator IC supporting up to four differential LVDS outputs, 100 MHz maximum output frequency, 50 ppm frequency stability over temperature, and I²C-based configuration. It serves as a system timing hub in industrial control backplanes requiring precise multi-clock domain synchronization.
For engineers reviewing the CY24293ZXCT datasheet, CY24293ZXCT pinout, CY24293ZXCT application, or CY24293ZXCT equivalent, key selection criteria include LVDS output count, I²C programmability, frequency stability across –40°C to +85°C, and compatibility with PCIe Gen2 reference clock requirements.
Technical Context
This device implements a PLL-based architecture with a fractional-N synthesizer core, enabling fine-grained frequency resolution down to 1 Hz step size. It accepts a single crystal or external CMOS clock input (1–50 MHz) and distributes synchronized, phase-aligned LVDS clocks across four independent output banks.
Configuration is performed via standard-mode I²C (up to 400 kHz), with non-volatile register storage allowing boot-time clock initialization without host intervention. Output skew between channels is specified at ≤50 ps, supporting tight timing budgets in high-speed serial interconnects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Count | 4 LVDS differential pairs - supports simultaneous clocking of multiple SerDes lanes or FPGAs |
| Max Output Freq | 100 MHz - meets PCIe Gen2 reference clock spec (100 MHz ±300 ppm) |
| Freq Stability | ±50 ppm over –40°C to +85°C - eliminates need for external oven-controlled crystal |
| Input Range | 1–50 MHz crystal or CMOS - enables flexible sourcing of reference sources |
| I²C Interface | Standard-mode (100 kHz) and fast-mode (400 kHz) - allows integration into legacy and modern MCU-based config systems |
| Phase Jitter (12 kHz–20 MHz) | 0.45 ps RMS - ensures low BER in 2.5 Gbps+ serial links |
| Supply Voltage | 3.3 V ±10% - compatible with standard industrial logic rails |
Pinout & Package
The CY24293ZXCT is housed in a 32-pin QFN package (5 mm × 5 mm, 0.5 mm pitch) with exposed thermal pad for enhanced power dissipation in continuous operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | Reference clock input | Accepts single-ended CMOS or crystal oscillator signal; internal buffer enables drive capability up to 50 MHz |
| SCL, SDA | I²C configuration interface | Two-wire bus for register programming; pull-up resistors required externally |
| OUT0+, OUT0− | Differential LVDS clock output 0 | 100 Ω differential termination required; supports 100 MHz LVDS signaling per JEDEC JESD79-3 |
| OUT1+, OUT1− | Differential LVDS clock output 1 | Independent enable/disable control per channel; phase alignment maintained vs. OUT0 |
| OUT2+, OUT2− | Differential LVDS clock output 2 | Configurable output divider (1–32) enables sub-harmonic generation for lower-speed peripherals |
| OUT3+, OUT3− | Differential LVDS clock output 3 | Programmable delay (0–15 ns in 125 ps steps) supports deskew in multi-FPGA systems |
| VDD, VDDIO | Power supply pins | Separate analog/digital supplies reduce noise coupling; decoupling caps mandatory per layout guidelines |
| GND, EPAD | Ground and thermal pad | EPAD must be soldered to PCB ground plane for thermal compliance and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Four independent LVDS outputs | Enables single-chip replacement of multiple discrete oscillators in multi-processor backplanes |
| Non-volatile configuration memory | Retains user-defined clock settings across power cycles-no boot firmware dependency |
| Programmable output skew | Per-channel delay tuning eliminates manual PCB trace length matching in FPGA clock trees |
| Low phase jitter (0.45 ps RMS) | Meets stringent jitter budget for PCIe Gen2/Gen3 and SATA III physical layer compliance |
| I²C address selection (A0/A1 pins) | Supports up to four identical devices on same bus-ideal for modular rack-mounted systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable clock generator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5338A-B-GM | 8-output, LVDS/LVPECL selectable; higher max freq (350 MHz); requires external EEPROM for NVM | Supports higher-speed SerDes (e.g., 10G KR); larger footprint (40-QFN) | Choose when >4 outputs or >100 MHz operation is required; adds complexity due to external memory |
| ICS8430I-01LFT | 4-output, fixed-frequency LVDS; no I²C; ±25 ppm stability; lower jitter (0.35 ps RMS) | Limited to static clock trees; no runtime reconfiguration | Choose for cost-sensitive, unchanging clock architectures where programmability is unnecessary |
Compared with Si5338A-B-GM and ICS8430I-01LFT, the CY24293ZXCT uniquely balances field-programmability, industrial-grade stability, and compact 4-output LVDS integration-making it optimal for space-constrained, reconfigurable embedded systems needing PCIe-compliant timing.

FAQ
What is the recommended power supply decoupling for CY24293ZXCT?
Use one 100 nF X7R ceramic capacitor per VDD/VDDIO pin placed within 2 mm of the pin, plus a shared 4.7 µF tantalum or polymer capacitor near the device. The exposed thermal pad must be connected to a solid ground plane with ≥6 thermal vias (0.3 mm diameter) for optimal noise suppression and thermal performance.
Can CY24293ZXCT generate spread-spectrum clocking (SSC)?
No. The CY24293ZXCT does not support spread-spectrum modulation. Its PLL architecture is optimized for low-jitter, fixed-frequency or programmable-frequency outputs only. For EMI reduction, external SSC-capable oscillators or downstream clock dividers with dithering must be used.
Is the I²C interface accessible during device operation?
Yes. The I²C interface remains fully functional during normal clock output operation, enabling dynamic reconfiguration of output frequencies, phases, or enable states without interrupting existing clock signals-critical for adaptive test equipment and reprogrammable industrial controllers.
Does CY24293ZXCT support differential input (LVDS or LVPECL)?
No. The CLKIN pin accepts only single-ended CMOS-level or crystal inputs (1–50 MHz). Differential reference inputs are not supported. For differential reference sources, an external level translator or dedicated buffer IC (e.g., SY89295L) is required before CLKIN.
