Skyworks Solutions Inc. SI5332CC09313-GM1R

Overview

SI5332CC09313-GM1R from Silicon Labs is a 6-output, any-frequency programmable clock generator in a 32-pin QFN package, supporting differential outputs up to 333.33 MHz with 190 fs RMS phase jitter (external crystal), PCIe Gen1–4 and SRIS compliance, and independent LVDS/LVPECL/HCSL/LVCMOS signal format per output. It serves as a single-device clock tree solution in high-density server and Ethernet switch timing subsystems.

For engineers reviewing the SI5332CC09313-GM1R datasheet, SI5332CC09313-GM1R pinout, SI5332CC09313-GM1R application, or SI5332CC09313-GM1R equivalent, key selection considerations include its 6-output 32-QFN footprint, external crystal input support (16–50 MHz), fractional synthesis capability up to 250 MHz, multi-bank VDDO supply flexibility (1.8/2.5/3.3 V), and I²C programmability for field reconfiguration.

Technical Context

The SI5332CC09313-GM1R implements a two-stage synthesis architecture: a wideband PLL locks to an external 16–50 MHz crystal, then feeds up to three independent MultiSynth fractional dividers and five integer dividers. Its cross-point multiplexer routes any synthesized or divided frequency to any of six differential outputs.

Each output supports user-configurable signal format (LVDS, LVPECL, HCSL, LVCMOS), adjustable skew (±245 ps in 35 ps steps), and synchronous enable/disable. Five universal hardware input pins support OE, spread-spectrum enable, or input selection - all defined via ClockBuilder Pro configuration.

Key Specifications

Pinout & Package

SI5332CC09313-GM1R uses a 5×5 mm, 32-pin QFN package (RoHS-6 compliant) with exposed thermal pad. Pin functions are defined per ClockBuilder Pro configuration; five universal hardware input pins support flexible system-level control.

Manufacturer

Silicon Labs is a fabless semiconductor company specializing in timing, wireless, and IoT solutions, with deep expertise in low-jitter clock generation and programmable frequency synthesis.

The Si5332 family was designed to replace multiple fixed-frequency oscillators and clock buffers with a single, software-configurable timing IC for high-speed digital systems-including datacenter, telecom infrastructure, and broadcast equipment-where flexibility, density, and jitter performance are critical.

FAQ

What is the maximum output frequency supported by SI5332CC09313-GM1R?

The SI5332CC09313-GM1R supports differential output frequencies up to 333.33 MHz in integer mode and up to 250 MHz in fractional synthesis mode. This is confirmed in the Si5332 Data Sheet Rev. 1.1, Section 1 (Features List) and Section 5 (Electrical Specifications), where the Si5332C grade is explicitly rated for 5–333.33 MHz output range. The SI5332CC09313-GM1R implements this full specification.

Does SI5332CC09313-GM1R include an embedded crystal?

No, SI5332CC09313-GM1R does not include an embedded crystal. It belongs to the Si5332C grade, which requires an external 16–50 MHz crystal connected to XA/XB pins. Embedded crystal variants (e.g., Si5332E/F/G/H) are designated with different suffixes and are physically distinct; the "C" in SI5332CC09313-GM1R confirms external crystal dependency.

Can SI5332CC09313-GM1R generate different output formats simultaneously?

Yes, SI5332CC09313-GM1R supports per-output signal format selection: LVDS, LVPECL, HCSL, or LVCMOS. Each of its six differential outputs can be independently configured-for example, OUT0 as LVDS, OUT2 as HCSL, and OUT4 as LVCMOS-enabling mixed-interface timing in a single device without external level-shifting.

What is the phase jitter performance of SI5332CC09313-GM1R?

SI5332CC09313-GM1R achieves 190 fs RMS phase jitter (12 kHz–20 MHz offset) when operating with an external crystal reference, as specified in the Si5332 Data Sheet Rev. 1.1, Table 5.1 (Phase Jitter Specifications). This meets PCIe Gen1–4 and SRIS compliance requirements for high-speed serial links.

How is SI5332CC09313-GM1R programmed and configured?

SI5332CC09313-GM1R is configured using Silicon Labs' ClockBuilder Pro software, which generates a custom part number (e.g., SI5332CC09313-GM1R) and factory-programs the device free of charge. It also supports in-system I²C programming (SCLK/SDATA pins) for runtime reconfiguration, profile switching, or field updates without reflashing hardware.
