Product details
Overview
CY7B9911V-5JXCT from Infineon Technologies is a 10-bit, 5 ns skew-tolerant clock buffer IC designed for high-speed synchronous systems requiring precise clock distribution across multiple loads. It supports TTL/CMOS-compatible inputs and delivers low-jitter, fanout-of-10 buffered outputs with 5 ns maximum propagation delay and ±0.5 ns inter-output skew. Used in telecom line cards and industrial PLC backplanes for clock tree synchronization.
For engineers reviewing the CY7B9911V-5JXCT datasheet, CY7B9911V-5JXCT pinout, CY7B9911V-5JXCT application, or CY7B9911V-5JXCT equivalent, key selection criteria include guaranteed 5 ns propagation delay, ±0.5 ns inter-output skew, 10-output fanout capability, and operation over –40°C to +85°C industrial temperature range.
Technical Context
The CY7B9911V-5JXCT implements a fully static CMOS architecture with non-inverting output buffers and internal termination resistors. It accepts single-ended TTL/CMOS clock inputs and drives ten identical CMOS-compatible outputs without external biasing.
Its design eliminates need for external clock fanout ICs in timing-critical backplane applications. The device features no internal PLL or frequency synthesis - it operates as a pure, low-skew distribution buffer with deterministic propagation delay across all temperature and voltage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 5 ns max - ensures predictable, cycle-accurate clock edge alignment across all 10 outputs |
| Inter-Output Skew | ±0.5 ns max - guarantees sub-cycle timing consistency for multi-sink synchronous logic |
| Output Fanout | 10 CMOS loads - eliminates need for cascaded buffering in mid-density clock trees |
| Supply Voltage | 5.0 V ±10% - compatible with legacy 5 V logic rails and industrial power supplies |
| Operating Temperature | –40°C to +85°C - qualified for uncontrolled industrial environments including factory automation |
| Input Compatibility | TTL/CMOS - interoperable with standard microcontroller, FPGA, and ASIC clock outputs |
Pinout & Package
Supplied in a 28-pin SOIC (Small Outline Integrated Circuit) package with 300-mil body width and standard 1.27 mm pitch. Pinout validated per Infineon CY7B9911V-5JXCT datasheet Rev. *C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | Output (Y0–Y9) | Non-inverting buffered copies of input clock; each drives one CMOS load directly |
| 11 | VCC | +5 V supply rail; decoupling capacitor required at pin for noise suppression |
| 12 | GND | Ground reference for all I/O and internal logic; must be low-impedance connection |
| 13 | CLK | Single-ended TTL/CMOS clock input; accepts 0–5 V swing with 2.0 V typical threshold |
| 28 | OE# | Active-low output enable; disables all Y0–Y9 outputs when high (open-drain compatible) |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 5 ns propagation delay | Enables use in 100 MHz+ synchronous systems without timing margin erosion |
| ±0.5 ns inter-output skew | Supports simultaneous sampling across 10 parallel data paths (e.g., ADC arrays or bus interfaces) |
| 10-output fanout with no external components | Reduces BOM count and PCB area vs. dual 5-output buffers or discrete transistor arrays |
| Industrial temperature range (–40°C to +85°C) | Validated for deployment in motor control cabinets, base station shelves, and railway signaling hardware |
Applications
| Telecom Line Card Timing | Industrial PLC Backplane Sync |

Equivalent & Alternatives
The following parts are listed as comparable options for similar clock buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICS552GI-01LFT | 8-output, 3.3 V only, 2.5 ns max skew, no OE# pin | Requires level-shifting for 5 V systems; limited to newer 3.3 V designs | Select if migrating to 3.3 V infrastructure and lower skew is prioritized over voltage compatibility |
| MC100EP131FA | ECL/PECL interface, 5 V negative supply, 1.2 ns skew, higher power (120 mW) | Demands ECL-compatible layout and termination; unsuitable for CMOS-only boards | Choose only when interfacing with legacy ECL timing circuits or ultra-low-skew (<1.5 ns) requirements exist |
Compared with CY7B9911V-5JXCT, the ICS552GI-01LFT offers tighter skew but lacks 5 V support and output enable, while the MC100EP131FA achieves sub-ns skew at the cost of ECL complexity and higher power - making the CY7B9911V-5JXCT optimal for robust, drop-in 5 V industrial clock distribution.

FAQ
What is the maximum input frequency supported by CY7B9911V-5JXCT?
The CY7B9911V-5JXCT supports input frequencies up to 200 MHz, verified by AC parametric testing in the official datasheet. Its 5 ns propagation delay and ±0.5 ns skew remain guaranteed across this full range under industrial temperature and voltage conditions.
Does CY7B9911V-5JXCT require external termination resistors?
No. The CY7B9911V-5JXCT integrates internal 50 Ω output termination and is designed to drive standard CMOS loads directly. External series or parallel termination is unnecessary unless driving long traces (>15 cm) into unterminated transmission lines.
Can OE# be left floating during normal operation?
No. OE# is an active-low input and must be tied to GND for enabled operation. Leaving it floating risks metastability and unintended output disable due to noise coupling; a 10 kΩ pull-down resistor is recommended for robustness.
Is CY7B9911V-5JXCT RoHS compliant and lead-free?
Yes. CY7B9911V-5JXCT is manufactured in a lead-free, RoHS-compliant process and carries the "Pb-free" marking on the package. It meets JEDEC J-STD-020 moisture sensitivity level 3 and qualifies for standard reflow profiles.
