Product details
Overview
CY22800FXC-001A from Cypress Semiconductor is a field-programmable universal clock generator with integrated PLL, supporting X2 multiplication mode for CLKIN (0.5–100 MHz) or crystal (8–30 MHz), delivering up to 200 MHz output on CLKA in commercial temperature range (0°C to 70°C), and featuring three programmable frequency select inputs (FS0–FS2) for dynamic configuration in consumer electronics timing systems.
For engineers reviewing the CY22800FXC-001A datasheet, CY22800FXC-001A pinout, CY22800FXC-001A application, or CY22800FXC-001A equivalent, this device offers reprogrammability (up to 100 times), spread spectrum disable capability, VCXO support, 3.3V operation, and 8-pin SOIC packaging - critical for HDTV, STB, and DVD recorder clock tree design where EMI reduction and multi-output flexibility are required.
Technical Context
The CY22800FXC-001A implements Cypress's proprietary integer-N PLL architecture with configurable feedback dividers and output dividers, enabling precise X2 multiplication of reference inputs. Its internal VCO operates across a wide tuning range to accommodate input frequencies from 0.5 MHz to 100 MHz while maintaining low jitter performance.
Frequency selection is managed via three digital control pins (FS0–FS2), allowing runtime switching among up to eight preloaded configurations. The device supports both crystal and single-ended external clock inputs on XIN/CLKIN, with XOUT providing buffered reference output - all operating at 3.3V supply with industrial-grade noise immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Frequency Range | Crystal: 8–30 MHz; CLKIN: 0.5–100 MHz - enables compatibility with common system clocks and low-cost crystals. |
| Output Frequency Range | Commercial: 1–200 MHz - supports high-speed pixel clocks (e.g., 74.25 MHz) and processor clocks (e.g., 133.33 MHz). |
| Supply Voltage | 3.3V ±5% - matches standard I/O voltage domains of modern SoCs and FPGAs without level-shifting. |
| Package | 8-pin SOIC - surface-mount compatible with automated PCB assembly and thermal profile constraints of consumer boards. |
| Reprogrammability | Up to 100 write cycles - allows iterative prototyping and field firmware updates without hardware change. |
| Spread Spectrum | Disabled (N) per Table 2 - eliminates intentional frequency modulation, ensuring deterministic timing for synchronous interfaces. |
| VCXO Support | Not enabled (N) in -001A configuration - simplifies design by removing analog tuning path and associated pullable crystal requirement. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), 150 mil width, JEDEC MS-012AC compliant, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XIN | Reference Input | Accepts either crystal (8–30 MHz) or external clock (0.5–100 MHz); internal oscillator circuitry drives XOUT when crystal used. |
| VDD | Power Supply | 3.3V main supply for core logic and output buffers; requires local 0.1 µF decoupling. |
| FS0/VCXO | Frequency Select 0 / VCXO Control | Digital select line in -001A mode; VCXO function disabled - used solely as FS0 for configuration indexing. |
| VSS | Ground | Analog/digital common ground reference; must be connected to low-impedance PCB plane. |
| CLKB/FS1 | Clock Output B / Frequency Select 1 | Dual-function pin: outputs CLKB (REFOUT) in -001A; also serves as FS1 for alternate configurations. |
| CLKA/FS0 | Clock Output A / Frequency Select 0 | Dual-function pin: delivers primary X2-multiplied output (1–200 MHz); doubles as FS0 in other modes. |
| CLKC/FS2/VSS | Clock Output C / Frequency Select 2 / Ground | In -001A, configured as VSS - third output disabled; pin shared with FS2 and ground to reduce package count. |
| XOUT | Reference Output | Buffered copy of XIN signal; left unconnected when external clock is used; essential for crystal-based designs. |
Key Features
| Feature | Design Value |
|---|---|
| Field-programmable configuration | 100-cycle EEPROM-based programming enables rapid iteration and post-silicon tuning without mask changes. |
| Three-frequency-select interface | FS0–FS2 pins allow real-time switching between up to eight stored clock profiles - ideal for multi-standard devices like STBs. |
| X2 multiplier architecture | Fixed 2× multiplication ratio simplifies timing analysis and reduces phase error accumulation vs. fractional-N synthesizers. |
| Low-jitter PLL synthesis | Integrated loop filter and optimized VCO deliver sub-100 ps RMS jitter - meets setup/hold margins for DDR and PCIe Gen1 interfaces. |
| Single-device inventory consolidation | One CY22800FXC-001A replaces multiple fixed-frequency oscillators in HDTV, STB, and DVDR platforms. |

Equivalent & Alternatives
CY22800FXC-001A is superseded by newer Cypress offerings with enhanced features; two verified drop-in alternatives exist for legacy design continuity and second-source assurance.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY22800FXC-002A | X3 multiplication mode; input CLKIN limited to 0.5–66.66 MHz; same 8-pin SOIC and 3.3V operation | Supports higher multiplication ratio but narrower input range - suitable when system clock is ≤66.66 MHz and 3× output needed | Select only if X3 ratio is required; not pin-compatible in functional behavior due to different PLL divisor mapping. |
| Si5338-A-GM | Four-output, I²C-programmable, fractional-N PLL; 1.8/2.5/3.3V selectable; 32-QFN package | Enables arbitrary frequency synthesis and dynamic reconfiguration; lacks built-in spread spectrum but supports external modulation | Choose for new designs requiring >2 outputs or sub-ppm accuracy; requires layout redesign and firmware integration effort. |
Compared with CY22800FXC-002A, the -001A provides wider input frequency support (up to 100 MHz) and simpler X2 ratio for deterministic timing; versus Si5338-A-GM, it trades programmability and output count for lower BOM cost, zero-config deployment, and proven reliability in volume consumer deployments.

FAQ
What is the maximum output frequency supported by CY22800FXC-001A?
The CY22800FXC-001A supports a maximum output frequency of 200 MHz on CLKA in commercial temperature range (0°C to 70°C). This is achieved using the X2 multiplication mode with a 100 MHz CLKIN or 30 MHz crystal input. Output jitter remains below 100 ps RMS at this rate, ensuring reliable timing margin for high-speed interfaces like DDR1 and PCI.
Does CY22800FXC-001A require an external crystal load capacitor?
Yes - when operated in crystal mode (XIN/XOUT), the CY22800FXC-001A requires external load capacitors matching the crystal's specified CL value (typically 12–18 pF). The internal oscillator circuit does not include adjustable capacitance; incorrect loading causes frequency inaccuracy or startup failure. No capacitors are needed in CLKIN mode.
Can FS0, FS1, and FS2 pins be left floating during operation?
No - all three frequency select pins (FS0–FS2) must be actively driven HIGH or LOW in CY22800FXC-001A configuration. Floating states may cause undefined output behavior or unintended configuration selection due to internal weak pull-downs insufficient for noise immunity. Tie unused pins to VSS or VDD via 10 kΩ resistors.
Is CY22800FXC-001A compatible with 2.5V or 1.8V I/O interfaces?
No - the CY22800FXC-001A is strictly a 3.3V-only device. Its input thresholds, output drive strength, and internal regulator are designed for 3.3V ±5% operation. Connecting to 2.5V or 1.8V logic without level translation risks input threshold violation, reduced noise margin, and potential damage from back-drive current if outputs sink into lower-voltage domains.
