Product details
Overview
CY25200KFZXCT from Infineon Technologies (formerly Cypress) is a programmable spread spectrum clock generator (SSCG) designed to reduce electromagnetic interference in high-speed digital systems. It synthesizes up to six output clocks (3–200 MHz), supports center/down spread modulation (±0.25%–±2.5% / –0.5%––5.0%), and features integrated PLL, programmable crystal load capacitance (12–60 pF), and dual VDDL/VDD output voltage domains (2.5 V/3.3 V). Used in PCIe, USB, and display subsystems for EMI compliance.
For engineers reviewing the CY25200KFZXCT datasheet, CY25200KFZXCT pinout, CY25200KFZXCT application, or CY25200KFZXCT equivalent, key selection criteria include spread percentage configurability, 31.5-kHz nominal modulation frequency, multi-output frequency select via CLKSEL, field-programmable Flash memory (100× reprogrammable), and TSSOP-16 package compatibility with commercial temperature range (0°C to 70°C).
Technical Context
The CY25200KFZXCT implements a proprietary analog PLL with VCO operating from 100–400 MHz, feeding six independently configurable output dividers. Input accepts either 8–30 MHz fundamental crystals (with programmable CXIN/CXOUT load caps) or 8–166 MHz external reference clocks.
All six outputs support spread spectrum modulation at fixed 31.5 kHz (also 30.1/32.9 kHz via configuration), with SSCLK1–SSCLK4 powered by VDDL (2.5 V or 3.3 V) and SSCLK5/SSCLK6 powered by VDD (3.3 V) - configurable as spread clocks, REFOUT copies, or control pins (CP2/CP3). Control logic includes OE, PD#, SSON, and CLKSEL functions mapped to four programmable pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 3–200 MHz per SSCLK output; enables timing synthesis for DDR, PCIe Gen2, and HDMI pixel clocks. |
| Spread Modulation | Center spread ±0.25% to ±2.5%, down spread –0.5% to –5.0%; reduces peak EMI amplitude by spectral energy redistribution. |
| Modulation Frequency | Nominal 31.5 kHz (also 30.1/32.9 kHz); avoids audible noise and aligns with CISPR 22/EN55022 conducted emission test bands. |
| Crystal Load Capacitance | Programmable 12–60 pF in 0.5-pF steps; eliminates external load capacitors and matches CL of 8–30 MHz fundamental crystals. |
| Input Frequency Range | 8–30 MHz crystal or 8–166 MHz reference clock; supports legacy XTAL-based designs and modern clock-tree integration. |
| Supply Voltages | VDD = 3.3 V (digital/PLL/analog), VDDL = 2.5 V or 3.3 V (SSCLK1–4 drive); enables mixed-voltage system interfacing without level shifters. |
| Operating Temperature | 0°C to 70°C commercial grade; validated for desktop, industrial HMI, and embedded computing environments. |
Pinout & Package
Package: 16-pin Thin Shrink Small Outline Package (TSSOP), 4.4 mm × 5.0 mm body, 0.65 mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XIN (Pin 1) | Clock input node | Accepts either crystal (8–30 MHz) or external reference (8–166 MHz); internal oscillator circuitry enabled when crystal used. |
| XOUT (Pin 16) | Clock output node | Crystal output; must be left floating when external clock is applied; connects to crystal's second terminal in XTAL mode. |
| VDD (Pin 2) | Digital power supply | 3.3-V supply for logic, PLL digital blocks, and SSCLK5/SSCLK6 outputs; decoupling required near pin. |
| CP0 (Pin 4) | Configurable control pin | Programmable as OE, PD#, SSON, or CLKSEL; PD# only available on CP0/CP1, not CP2/CP3. |
| AVDD (Pin 3) | Analog PLL power | 3.3-V dedicated supply for PLL analog circuitry; requires separate low-noise filtering from VDD. |
| VSS (Pin 13) | Digital ground | Main digital return path; must be connected to PCB ground plane with low-inductance trace. |
| AVSS (Pin 5) | Analog ground | Dedicated analog ground for PLL; isolated from digital ground except at single-point star connection. |
| VDDL (Pin 11) | Output driver supply | 2.5-V or 3.3-V supply for SSCLK1–SSCLK4; sets output voltage level and max frequency (166 MHz at 2.5 V). |
| VSSL (Pin 6) | VDDL ground | Return path for VDDL supply; must be tied to local ground plane adjacent to VDDL decoupling capacitor. |
| SSCLK1–SSCLK4 (Pins 7,8,9,12) | Spread spectrum outputs | Fixed-function SSCG outputs driven by VDDL; support full 3–200 MHz range at 3.3 V, up to 166 MHz at 2.5 V. |
| SSCLK5/REFOUT/CP2 (Pin 14) | Multi-function terminal | Configurable as spread clock, buffered reference copy (REFOUT), or control pin CP2; driven by VDD (3.3 V). |
| SSCLK6/REFOUT/CP3 (Pin 15) | Multi-function terminal | Same functionality as Pin 14; allows dual REFOUT generation or independent control signal routing. |
Key Features
| Feature | Design Value |
|---|---|
| Field-programmable Flash memory | 100× reprogrammable configuration storage enables rapid EMI tuning during EMC validation without hardware change. |
| Integrated crystal load capacitance | 12–60 pF programmable in 0.5-pF steps eliminates external capacitors and reduces BOM count and layout sensitivity. |
| Dual-output voltage domain | VDDL (2.5 V/3.3 V) and VDD (3.3 V) supplies allow SSCLK1–4 to interface with 2.5-V logic while SSCLK5/6 drive 3.3-V receivers. |
| CLKSEL frequency select | Hardware pin toggles between two pre-programmed output frequencies derived from same PLL base - no I²C/SPI overhead. |
| Multi-function output pins | Pins 14 and 15 serve as SSCLK, REFOUT, or CP2/CP3 - increases design flexibility without adding external logic. |

Equivalent & Alternatives
Two verified alternatives exist for CY25200KFZXCT: the Si5351A from Silicon Labs and the ICS843002AGI from Renesas. Both provide spread spectrum capability but differ in architecture, pin compatibility, and programming interface.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5351A-B-GM | Uses fractional-N synthesizer (not integer PLL); 8-output, I²C-programmable; no integrated crystal load caps; requires external 25-MHz XTAL. | Supports wider output range (8 kHz–210 MHz) but lacks native REFOUT function; unsuitable for designs requiring pin-compatible drop-in replacement. | Select when flexible multi-frequency synthesis and software-defined clock tree are prioritized over hardware control pins and crystal integration. |
| ICS843002AGI-01LFT | Fixed-function SSCG (no field programming); 3-output; 3.3-V only; spread fixed at ±0.25% center; no CLKSEL or VDDL option. | Lower cost and smaller footprint (8-pin SOIC), but cannot replicate CY25200's dual-voltage outputs or field-tunable spread settings. | Select for cost-sensitive, high-volume applications where EMI margin is sufficient with fixed ±0.25% spread and no need for post-silicon tuning. |
Compared with Si5351A and ICS843002AGI, CY25200KFZXCT uniquely combines field-programmable Flash, integrated crystal tuning, hardware CLKSEL, and dual-supply outputs - making it optimal for prototyping, EMC-critical designs, and systems requiring both REFOUT and SSCLK on same device.

FAQ
What is the maximum output frequency when VDDL is set to 2.5 V?
The CY25200KFZXCT supports up to 166 MHz on SSCLK1–SSCLK4 when VDDL is supplied at 2.5 V. This limit arises from driver strength and slew rate constraints at lower voltage; operation above 166 MHz requires VDDL = 3.3 V. The specification is confirmed in Section 7.2 of the Rev. *M datasheet under "AC Electrical Specifications".
Can SSCLK5 and SSCLK6 operate simultaneously as both REFOUT and control pins?
No. Each of SSCLK5 (Pin 14) and SSCLK6 (Pin 15) is individually configurable as either an SSCLK output, a REFOUT buffer, or a control pin (CP2 or CP3), but not more than one function at a time. Configuration is stored in nonvolatile Flash and set during programming - runtime reconfiguration is not supported.
Is the 31.5-kHz modulation frequency fixed or adjustable?
The nominal modulation frequency is 31.5 kHz and is factory-default, but two alternatives - 30.1 kHz and 32.9 kHz - are available via Cypress configuration software (CY3672 programmer + CY3695 adapter). These values are implemented in firmware and do not require hardware changes.
Does CY25200KFZXCT require external crystal load capacitors?
No. The device integrates programmable crystal load capacitance (CXIN/CXOUT) from 12 pF to 60 pF in 0.5-pF steps, eliminating external capacitors. When using an external reference clock instead of a crystal, CXIN/CXOUT must be set to minimum (12 pF) and XOUT left unconnected.
