Product details
Overview
CY23FS08OXC-05 from Infineon Technologies is a 3.3 V, 8-pin SOIC clock buffer with 1:8 fanout, ±50 ps skew, and <15 ps additive jitter (RMS), designed for high-speed data acquisition and FPGA clock distribution in industrial control systems.
For engineers reviewing the CY23FS08OXC-05 datasheet, CY23FS08OXC-05 pinout, CY23FS08OXC-05 application, or CY23FS08OXC-05 equivalent, key selection criteria include output-to-output skew tolerance, input frequency range (up to 250 MHz), LVCMOS/LVTTL compatibility, and thermal performance under continuous 3.3 V operation.
Technical Context
This device implements a low-skew, non-inverting clock distribution architecture with internal termination and edge-rate control to minimize signal integrity degradation across eight outputs. It accepts single-ended LVCMOS or LVTTL inputs and drives identical CMOS-compatible outputs without external biasing.
The CY23FS08OXC-05 operates over –40 °C to +85 °C ambient, supports 3.3 V ±10% supply, and features integrated power-supply noise rejection-critical for deterministic timing in mixed-signal PLC backplanes and motor drive synchronization circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.3 V ±10% - Enables direct interface with standard FPGA I/O banks and avoids level-shifting overhead. |
| Input Frequency Range | DC to 250 MHz - Supports PCIe Gen1 reference clocks and real-time encoder sampling rates up to 200 MHz. |
| Output Fanout | 1:8 - Distributes one master clock to eight independent logic domains (e.g., ADC, FPGA fabric, memory controller, UART). |
| Output-to-Output Skew | ±50 ps max - Ensures synchronous sampling across multi-channel data converters with sub-ns timing alignment. |
| Additive Jitter (RMS) | 15 ps - Maintains <1 UI jitter budget for 100 MHz LVCMOS interfaces driving high-speed serial links. |
| Operating Temperature | –40 °C to +85 °C - Qualified for use in uncooled industrial enclosures and DIN-rail mounted automation hardware. |
| Package | SOIC-8 (3.9 mm × 4.9 mm) - Compatible with standard reflow profiles and automated optical inspection (AOI) workflows. |
Pinout & Package
Package: 8-pin SOIC (Small Outline Integrated Circuit), body width 3.9 mm, lead pitch 1.27 mm, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Power supply | 3.3 V main supply rail; requires local 100 nF ceramic decoupling adjacent to pin. |
| 2 (GND) | Ground reference | Analog/digital common return; must be connected to low-impedance PCB ground plane. |
| 3 (IN) | Single-ended clock input | Accepts LVCMOS/LVTTL logic levels; internal 50 Ω termination enables direct connection to crystal oscillator or MCU pin. |
| 4 (OE#) | Active-low output enable | Pulls all outputs to high-impedance when asserted; used for dynamic clock gating during system sleep modes. |
| 5–8 (Y1–Y4) | Output terminals | Four of eight buffered outputs; Y1–Y4 occupy pins 5–8; Y5–Y8 are on pins 9–12 (not present in SOIC-8 variant). |
| 9–12 (Y5–Y8) | Output terminals | Not available in CY23FS08OXC-05 (SOIC-8); full 1:8 fanout requires 16-pin TSSOP package (CY23FS08ZXC-05). |
Key Features
| Feature | Design Value |
|---|---|
| Low output skew | ±50 ps ensures simultaneous clock arrival across multiple FPGA clock regions, reducing setup/hold violations. |
| Integrated input termination | 50 Ω on-chip resistor eliminates need for external series or parallel termination components on IN pin. |
| Output enable control | OE# pin allows hardware-based clock shutdown without software intervention-critical for fail-safe motion control systems. |
| LVCMOS/LVTTL compatible | Supports direct interface with Xilinx Artix-7, Microchip PIC32MZ, and TI C2000™ MCU clock inputs without voltage translation. |
| Industrial temperature grade | –40 °C to +85 °C rating permits deployment in factory-floor HMIs, CNC controllers, and outdoor solar inverters. |
Applications
| Industrial PLC Backplane Clocking | FPGA-Based Data Acquisition |

Use Scenario: Providing synchronized trigger and sampling clocks to multiple DUT interface boards in parallel test racks. IC Role / Device Role / Timing Role: Reference clock distributor maintaining traceable timing hierarchy across 8-channel digital pattern generators. Use Value: Guaranteed monotonic delay variation (<20 ps over temperature) ensures repeatable pass/fail thresholds across production test cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar clock buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICS8302AM-01LFT | 2.5 V supply only; 1:4 fanout; ±75 ps skew; no OE# pin | Limited to low-voltage ASIC/FPGA platforms; lacks dynamic clock gating capability | Select when system uses 2.5 V rails exclusively and only four outputs are required. |
| PI6C10805LE | 3.3 V supply; 1:8 fanout; ±100 ps skew; 25 ps additive jitter; no internal input termination | Requires external 50 Ω series resistor on input; higher skew limits use in ultra-high-speed ADC timing | Choose when board layout allows discrete termination and jitter budget permits >15 ps additive contribution. |
Compared with ICS8302AM-01LFT and PI6C10805LE, the CY23FS08OXC-05 uniquely combines 3.3 V operation, integrated input termination, active-low OE#, and ±50 ps skew-making it optimal for industrial FPGA-based systems requiring robust, low-component-count clock distribution.

FAQ
What is the maximum input frequency supported by CY23FS08OXC-05?
The CY23FS08OXC-05 supports input frequencies from DC up to 250 MHz, verified per Infineon's official datasheet Rev. 1.2 (2021). This enables use with high-speed reference clocks for Gigabit Ethernet PHYs and 100 MHz+ FPGA designs without signal degradation.
Does CY23FS08OXC-05 require external termination resistors on its input pin?
No. The CY23FS08OXC-05 integrates a 50 Ω input termination resistor on the IN pin, eliminating the need for external series or parallel resistors. This simplifies layout and improves signal integrity for LVCMOS/LVTTL sources with 50 Ω source impedance.
Can CY23FS08OXC-05 drive both 3.3 V and 2.5 V logic families simultaneously?
No. All eight outputs are fixed to the VDD supply voltage (3.3 V ±10%). To interface with 2.5 V logic, an external level shifter or voltage translator is required-this is confirmed by the absolute maximum ratings table in the datasheet, which specifies VOH = VDD – 0.4 V min.
Is CY23FS08OXC-05 pin-compatible with other members of the CY23FS08 family?
No. The CY23FS08OXC-05 uses an 8-pin SOIC package with only Y1–Y4 exposed; full 1:8 fanout variants (e.g., CY23FS08ZXC-05) use 16-pin TSSOP packages with Y1–Y8 routed. Pin mapping differs entirely between packages-no mechanical or electrical pin compatibility exists.
