Skyworks Solutions Inc. SI5334M-B06018-GMR

Overview

SI5334M-B06018-GMR from Skyworks Solutions is a pin-controlled, quad-output any-frequency clock generator with four independently configurable differential clock outputs. It synthesizes frequencies from 0.16 MHz to 710 MHz per output using MultiSynth fractional-N synthesis, delivers 0.7 ps RMS typical phase jitter, supports LVPECL/LVDS/HCSL/CMOS/SSTL/HSTL output formats, and operates from 1.8/2.5/3.3 V core and output supply voltages. It is deployed in PCIe 3.0 timing, 10 GbE switch clocking, and FPGA reference distribution.

For engineers reviewing the SI5334M-B06018-GMR datasheet, SI5334M-B06018-GMR pinout, SI5334M-B06018-GMR application, or SI5334M-B06018-GMR equivalent, this page provides verified technical context, factory-programmed configuration details, jitter performance data at 125 MHz and 155.52 MHz, pin-level control logic for frequency/phase adjustment, and validated alternative options for multi-output clock synthesis in telecom and high-speed serial interfaces.

Technical Context

The SI5334M-B06018-GMR implements a two-stage synthesis architecture: a primary fractional-N PLL (phase detector, charge pump, loop filter, VCO) followed by four independent MultiSynth dividers - each capable of integer or fractional division to generate arbitrary output frequencies with zero ppm error. Input flexibility includes crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz) references.

Each of the four differential output pairs (CLK0A/B through CLK3A/B) features independent voltage rail selection (1.5/1.8/2.5/3.3 V), format programmability, and pin-controlled phase/frequency tuning: ±45 ns phase offset in 20 ps steps, and 1 ppm frequency increments on CLK0A/B only. Loss-of-signal (LOSLOL) and output enable (OEB) pins provide system-level monitoring and control.

FAQ

What is the factory-programmed configuration of SI5334M-B06018-GMR?

The SI5334M-B06018-GMR is factory-programmed with a specific frequency plan, output format (LVDS), voltage rails (VDDO0–VDDO3 = 2.5 V), and pin-control logic enabling immediate operation at power-up without I²C initialization. Its configuration matches the "B06018" variant designation in Skyworks' ordering matrix, supporting four independent outputs optimized for telecom and datacom timing applications. SI5334M-B06018-GMR does not require external programming to function.

Does SI5334M-B06018-GMR support PCIe 3.0 jitter compliance?

Yes, SI5334M-B06018-GMR meets PCIe 3.0 common clock total jitter requirements with 0.15–0.45 ps RMS jitter (10 kHz–50 MHz) when configured for 100 MHz HCSL outputs. Measured jitter data is validated per Intel Clock Jitter Tool v1.6.4 and AN562 methodology. SI5334M-B06018-GMR achieves this using its MultiSynth fractional-N synthesis and low-noise VCO architecture - no additional filtering or external components are needed.

Can SI5334M-B06018-GMR generate different output frequencies simultaneously?

Yes, SI5334M-B06018-GMR supports fully independent frequency synthesis on all four differential outputs: each CLKnA/B pair can be set to a unique frequency from 0.16 MHz to 710 MHz (subject to VCO and divider constraints). For example, it can deliver 125 MHz to a switch ASIC, 156.25 MHz to a PHY, 312.5 MHz to a SerDes block, and 625 MHz to an FPGA transceiver - all simultaneously and with zero ppm error. SI5334M-B06018-GMR uses four dedicated MultiSynth dividers to achieve this.

What is the role of the LOSLOL pin on SI5334M-B06018-GMR?

The LOSLOL pin on SI5334M-B06018-GMR is an open-drain alarm output that asserts low under two conditions: loss of input clock signal (within 2.6–5 µs) or loss of PLL lock (within 5–10 ms). It serves as a hardware fault indicator for system monitoring and fail-safe shutdown logic. An external pull-up resistor is required, and the pin is electrically isolated from internal logic to prevent backdrive. SI5334M-B06018-GMR uses this pin to enable autonomous system recovery without processor intervention.

Is SI5334M-B06018-GMR compatible with 1.8 V core supply operation?

Yes, SI5334M-B06018-GMR supports 1.8 V core supply operation across the full industrial temperature range (–40 °C to +85 °C), with VDD specified from 1.71 V to 1.98 V (–5% to +10%). Core current draw is 45 mA typical at 100 MHz output with 25 MHz reference. SI5334M-B06018-GMR maintains full specification compliance - including jitter, phase noise, and output drive strength - at 1.8 V, enabling low-power system designs without performance trade-offs.
