Product details
Overview
SI5332BC09229-GM3 from Silicon Labs is a 12-output, factory-programmed, any-frequency clock generator with MultiSynth™ fractional synthesis, delivering 190 fs RMS phase jitter (external crystal), 5–333.33 MHz differential output range, and independent per-output signal format configuration (LVDS/LVPECL/HCSL/LVCMOS) for mixed-supply timing systems.
For engineers reviewing the SI5332BC09229-GM3 datasheet, SI5332BC09229-GM3 pinout, SI5332BC09229-GM3 application, or SI5332BC09229-GM3 equivalent, this device supports PCIe Gen4-compliant low-jitter clock trees in Ethernet switches, servers, and small cell base stations requiring multi-voltage bank outputs and I²C programmability.
Technical Context
The SI5332BC09229-GM3 implements a wideband PLL coupled with three independent MultiSynth fractional synthesis paths and five integer dividers, enabling simultaneous generation of up to twelve non-integer-related frequencies with 0 ppm synthesis error. Its architecture includes a cross-point mux routing any synthesized or divided frequency to any output bank.
This 48-pin QFN device features four output banks (A–D), each with shared VDDO supply pins supporting 1.8/2.5/3.3 V differential or 1.5/1.8/2.5/3.3 V LVCMOS levels, plus seven user-configurable hardware input pins for OE, spread-spectrum enable, or input selection - all defined via ClockBuilder Pro and stored in NVM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Count | 12 differential outputs (24 LVCMOS possible), organized in 4 voltage-isolated banks (A–D) |
| Phase Jitter (RMS) | 190 fs (measured over 12 kHz–20 MHz offset, external 16–50 MHz crystal reference) |
| Output Frequency Range | Differential: 5–333.33 MHz; LVCMOS: 5–170 MHz - supports PCIe Gen1–4, SRIS, and Ethernet sync |
| Synthesis Accuracy | 0 ppm frequency error - eliminates need for trimming or calibration in production |

Pinout & Package
SI5332BC09229-GM3 is housed in a 6×6 mm, 48-pin QFN package (RoHS-6 compliant) with exposed thermal pad, designed for high-density PCB layouts and optimal thermal dissipation in timing-critical applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT0 / OUT0b | Differential clock output pair (Bank A) | Individually configurable signal format (LVDS/LVPECL/HCSL/LVCMOS); skew adjustable in 35 ps steps |
| VDDO0 | Output bank supply (Bank A) | Independent 1.8/2.5/3.3 V rail - isolates Bank A from other banks' noise and voltage domains |

| XA / XB | External crystal connection | Supports 16–50 MHz fundamental-mode crystals; internal load capacitance selectable (2–30 pF) or disabled |
| SCLK / SDATA | I²C serial interface | Standard two-wire bus (400 kHz max); enables in-system reconfiguration without reflashing NVM |
| OEb | Hardware output enable (active-low) | Configurable via ClockBuilder Pro to control one or more output banks - provides fast, glitch-free disable |
Key Features
| Feature | Design Value |
|---|---|
| MultiSynth™ fractional synthesis | Enables any-frequency generation up to 250 MHz on any output with zero ppm error - replaces multiple fixed-frequency oscillators |
| Per-output signal format selection | Each of 12 outputs independently set to LVDS, LVPECL, HCSL, or LVCMOS - eliminates external level translators in heterogeneous systems |
| Four isolated VDDO banks | Supports concurrent 1.8 V, 2.5 V, and 3.3 V clock domains - simplifies timing interface to multi-rail FPGAs, ASICs, and PHYs |
| Programmable spread spectrum | Down or center modulation (0.1–2.5% at 30–33 kHz) - reduces EMI peak emissions without affecting system timing margins |
| Multi-profile configuration storage | Up to 16 configurations stored in NVM; enables rapid, glitchless on-the-fly frequency changes between pre-defined modes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable clock generator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si5332BC09228-GM3 | Same 48-QFN package and Si5332B family, but configured for 8-output mode (GM2 footprint compatibility) | Limited to 8 differential outputs; reduced bank count (2 banks vs. 4) - insufficient for full 12-output server clock trees | Select only when board layout uses GM2 land pattern or application requires ≤8 outputs with identical jitter specs |
| Si5338A-D-GM | 8-output, 32-QFN; 195 fs RMS jitter; supports only integer synthesis (no fractional MultiSynth) | No non-integer frequency support; lacks per-output format flexibility and multi-bank isolation - unsuitable for mixed-voltage PCIe Gen4 | Consider for cost-sensitive, fixed-frequency applications where 0 ppm error and 12-output density are not required |
Compared with SI5332BC09229-GM3, Si5332BC09228-GM3 offers identical jitter and programming but fewer outputs and banks, while Si5338A-D-GM trades synthesis flexibility and output count for lower pin count and cost - making SI5332BC09229-GM3 optimal for high-density, multi-standard timing systems.

FAQ
What is the phase jitter performance of the SI5332BC09229-GM3?
The SI5332BC09229-GM3 delivers 190 fs RMS phase jitter (12 kHz–20 MHz integration bandwidth) when using an external 16–50 MHz crystal reference. This specification is measured under standard conditions per the Si5332 Data Sheet Rev. 1.1 and meets PCIe Gen4 SRIS requirements. The SI5332BC09229-GM3 does not include an embedded crystal, so jitter performance assumes proper PCB layout for external crystal placement and grounding.
Does the SI5332BC09229-GM3 support spread spectrum clocking?
Yes, the SI5332BC09229-GM3 supports both down-spread and center-spread spectrum modulation from –0.1% to –2.5% at 30–33 kHz, implemented via its MultiSynth™ engine for precise EMI reduction. Spread spectrum can be enabled either through I²C register writes or by assigning a universal hardware input pin (e.g., Input1) as SS_EN in ClockBuilder Pro - no external components are required.
Can the SI5332BC09229-GM3 generate non-integer output frequencies?
Yes, the SI5332BC09229-GM3 uses MultiSynth™ fractional synthesis to generate any output frequency from 5 to 250 MHz with zero ppm error - including non-integer multiples like 156.25 MHz, 212.5 MHz, or 307.2 MHz. This capability is inherent to the Si5332B grade and is pre-programmed into the SI5332BC09229-GM3's NVM during factory configuration.
What output signal formats does the SI5332BC09229-GM3 support?
The SI5332BC09229-GM3 supports LVDS, LVPECL, HCSL, and LVCMOS on each of its 12 differential outputs - configurable individually per output via ClockBuilder Pro or I²C. LVCMOS outputs operate from 1.5 V to 3.3 V (set by respective VDDO), while differential formats support 1.8/2.5/3.3 V common-mode levels - all verified in the SI5332BC09229-GM3's final factory configuration.
Is the SI5332BC09229-GM3 pin-compatible with other Si5332 variants?
The SI5332BC09229-GM3 uses the 48-pin QFN (GM3) package and shares identical pinout and footprint with all Si5332-GM3 variants (e.g., Si5332AC09229-GM3, Si5332CC09229-GM3). However, electrical behavior (e.g., synthesis mode, output count, embedded crystal) differs by grade letter (A/B/C/D/E/F/G/H) and NVM configuration - mechanical compatibility does not guarantee functional interchangeability.
