Product details
Overview
CY27410FLTXIT from Infineon Technologies (formerly Cypress) is a 4-PLL spread-spectrum clock generator with fractional-N synthesis, supporting up to 12 configurable outputs (8 differential + 4 single-ended), RMS phase jitter ≤1 ps (12 kHz–20 MHz), PCIe 3.0/USB 3.0/SATA 2.0 compliance, and VCXO tuning ±120 ppm - deployed in high-speed serial interface timing for industrial and consumer embedded systems.
For engineers reviewing the CY27410FLTXIT datasheet, CY27410FLTXIT pinout, CY27410FLTXIT application, or CY27410FLTXIT equivalent, key selection criteria include differential output skew (<100 ps within bank), I²C programmability, spread-spectrum profile configurability (0.1%–5%, down/center), and dual-bank output routing with zero-delay buffer capability.
Technical Context
The CY27410FLTXIT integrates four independent fractional-N PLLs, each feeding four synchronized dividers to generate phase-aligned outputs with glitch-free transitions. Each PLL supports VCXO control via VIN and spread-spectrum modulation with selectable Lexmark or logic profiles.
Input flexibility includes crystal (8–48 MHz), LVCMOS reference (8–250 MHz), or differential reference (8–700 MHz); outputs support LVDS/LVPECL/HCSL/CML (25–700 MHz) and LVCMOS (3 MHz–250 MHz plus one 1 kHz–8 MHz low-frequency output).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PLL count | Four independent fractional-N PLLs enabling simultaneous multi-frequency synthesis with zero-ppm error |
| Max output frequency | 700 MHz differential (LVDS/LVPECL/HCSL/CML) - supports PCIe Gen3 and 10GbE line rates |
| RMS phase jitter | ≤1 ps (12 kHz–20 MHz offset) - meets PCIe 3.0 and USB 3.0 jitter budgets |
| Output configuration | Up to 12 outputs split across two banks (6 per bank), with 8 differential pairs + 4 LVCMOS - enables mixed-signaling clock trees |
| VCXO range | ±120 ppm tuning resolution (0.23 ppm steps) via analog VIN input - used for audio/video sync in digital TV systems |
| Spread-spectrum | Configurable 0.1%–5% down-spread or center-spread in 0.1% increments - reduces EMI without requiring board-level filtering |
| I²C interface | Fast-mode (400 kbps), 7-bit address (default 0x69), onboard volatile/nonvolatile register programming - enables field reconfiguration |
Pinout & Package
Package: 48-pin QFN (7 × 7 × 1.0 mm), thermally enhanced, RoHS-compliant, with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| XIN / XOUT | Crystal oscillator interface | Accepts 8–48 MHz fundamental-mode crystal; internal oscillator circuit eliminates need for external XTAL driver |
| IN1P / IN1N / IN2P / IN2N | Differential reference inputs | Support LVPECL/LVDS/CML/HCSL; AC-coupled; IN2 usable as feedback for ZDB mode |
| VIN | VCXO control voltage input | Analog input (0–VDD) controlling PLL1 fractional divider for ±120 ppm frequency pull |
| FS0 / FS1 / FS2 | Frequency select control | 3-bit binary input selecting among eight preloaded register sets for on-the-fly output frequency switching |
| SCLK / SDAT | I²C serial interface | Standard bidirectional I²C bus (400 kbps) for full device configuration and partial updates |
| OUT11P–OUT14N / OUT21P–OUT24N | Differential output pairs | Each pair configurable as LVDS/LVPECL/HCSL/CML; <100 ps skew within bank ensures timing integrity |
| OUT15 / OUT16 / OUT25 / OUT26 | LVCMOS outputs | Single-ended outputs supporting 3 MHz–250 MHz; one dedicated low-frequency output (1 kHz–8 MHz) |
Key Features
| Feature | Design Value |
|---|---|
| Zero-delay buffer (ZDB) mode | Configurable via feedback loop on IN2; supports integer-N PLL operation for exact 1:1 or frequency-multiplying clock replication |
| Non-zero delay buffer (NZDB) mode | Bypasses PLL entirely; provides level translation and selectable input routing with programmable delay (0–4 × VCO/2 cycles) |
| Early/late phase adjustment | Per-output delay circuit enables fine-grained phase alignment (e.g., deskew between PCIe REFCLK and TX/RX clocks) |
| On-chip NV memory | Stores eight complete configuration sets; enables boot-time initialization without host processor involvement |
Applications
| PCIe Gen3 Clocking | USB 3.0 Hub Timing |
|---|---|
Use Scenario: Generating synchronized 100-MHz HCSL REFCLK and 250-MHz PHY clocks for PCIe Gen3 endpoint with spread-spectrum EMI reduction. IC Role / Device Role / Timing Role: Primary clock generator providing phase-aligned, low-jitter differential clocks with down-spread profile applied identically across all outputs.

IC Role / Device Role / Timing Role: VCXO-controlled PLL1 cascaded to PLL2/PLL3 to produce harmonically related outputs with sub-ppm frequency correlation. Use Value: Maintains lip-sync accuracy across HDMI/SDI outputs by locking both domains to same 27-MHz VCXO source with <200-fs jitter accumulation. | Use Scenario: Providing 125-MHz LVDS clocks to multiple 10GbE PHYs and 25-MHz management clocks to switch fabric controllers in ruggedized industrial switch. IC Role / Device Role / Timing Role: Dual-bank clock distributor delivering isolated, low-skew clocks to separate data and control planes with independent power domains (VDDIO_D1/VDDIO_S1). Use Value: Enables deterministic latency across 10GbE lanes while supporting -40°C to +85°C operation via industrial-grade qualification and thermal QFN package. |
Equivalent & Alternatives
Two verified alternatives exist for design migration or second-source assurance:
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5341-B-GM | 12-output, 4-input any-rate clock generator with integrated jitter cleaners; higher integration but no VCXO input | Superior jitter performance (60 fs) but lacks analog VCXO tuning; requires external loop filter for PLL stability | Choose for ultra-low-jitter applications where VCXO sync is unnecessary and jitter budget is <0.5 ps RMS |
| ICS8430I-01T | 4-output, 2-PLL spread-spectrum generator; fixed architecture, no I²C programmability, no VCXO | Limited to 4 outputs and basic spread-spectrum; no frequency-select pins or onboard NV memory | Choose only for cost-sensitive, fixed-function designs requiring minimal features and no field reconfiguration |
Compared with Si5341-B-GM and ICS8430I-01T, the CY27410FLTXIT uniquely balances programmability (I²C + FS pins), VCXO support, and dual-bank flexibility - making it optimal for mid-tier industrial and consumer platforms needing moderate integration with analog tuning and EMI control.

FAQ
What is the maximum differential output frequency supported by CY27410FLTXIT?
The CY27410FLTXIT supports differential output frequencies up to 700 MHz using LVDS, LVPECL, HCSL, or CML signaling - validated per AC output specifications in Rev. *M datasheet (p.16). This enables direct use in PCIe Gen3 (100 MHz REFCLK × 10 = 1 GHz lane rate, with 700 MHz clock domain sufficient for PHY timing).
Does CY27410FLTXIT support zero-delay buffer functionality with feedback from an external clock source?
Yes - the CY27410FLTXIT implements zero-delay buffer (ZDB) mode by routing one of its outputs (e.g., OUT11) back to IN2 as a feedback signal. This requires integer-N PLL configuration and enables exact 1:1 clock replication or frequency multiplication (e.g., 100 MHz in → 200 MHz out) with sub-cycle phase alignment.
Can the spread-spectrum profile be disabled or changed dynamically during operation?
Yes - spread-spectrum can be enabled/disabled and its parameters (amplitude, direction, profile type) modified in real time via I²C register writes or static control using FS pins. The device retains full spread-spectrum compliance (PCIe/SATA) when active and delivers clean spectral content when disabled.
Is the 48-pin QFN package of CY27410FLTXIT compatible with standard reflow profiles?
Yes - the 7 × 7 × 1.0 mm QFN package complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles (peak 260°C, 60-second duration above 217°C), as specified in the "Solder Reflow Specifications" section (p.26) of the official datasheet.
