Skyworks Solutions Inc. SI5334M-B06024-GM

Overview

SI5334M-B06024-GM from Skyworks Solutions is a pin-controlled, any-frequency quad clock generator IC 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 supplies - deployed in PCIe 3.0 timing, FPGA clocking, and broadcast video systems.

For engineers reviewing the SI5334M-B06024-GM datasheet, SI5334M-B06024-GM pinout, SI5334M-B06024-GM application, or SI5334M-B06024-GM equivalent, key selection criteria include its 4-output independent frequency synthesis up to 710 MHz, zero-ppm accuracy, <20 ps phase step resolution, spread-spectrum capability on 100 MHz outputs, and 24-QFN package compatibility with high-density PCB layouts.

Technical Context

The SI5334M-B06024-GM integrates a fully on-chip fractional-N PLL with VCO, loop filter, and four independent MultiSynth output dividers enabling non-integer frequency synthesis on each of four differential outputs. Its input stage accepts 8–30 MHz crystals or 5–710 MHz differential/single-ended clocks, with R-divider options for reference scaling.

Each output driver features independent voltage supply (1.5/1.8/2.5/3.3 V), format selection (LVPECL/LVDS/HCSL/CMOS/SSTL/HSTL), and programmable phase offset (±45 ns, <20 ps steps). The device operates in pin-control mode only - no I²C interface - and supports optional zero-delay feedback via FDBK/FDBKB pins.

Key Specifications

Pinout & Package

SI5334M-B06024-GM is housed in a 24-lead, 4 mm × 4 mm QFN package with exposed thermal pad. Pin assignments follow Skyworks' standard Si5334 pinout: dual differential inputs (IN1/IN2, IN5/IN6), single-ended inputs (IN3, IN4), four differential output pairs (CLK0A/B–CLK3A/B), dedicated LOSLOL alarm output, OEB enable control, and separate VDD (core) and VDDOx (output buffer) supplies.

FAQ

What input reference sources does the SI5334M-B06024-GM support?

The SI5334M-B06024-GM supports multiple reference inputs: an 8–30 MHz crystal directly connected to IN1/IN2, or AC-coupled differential clocks (5–710 MHz) on IN1/IN2 or IN5/IN6, or DC-coupled single-ended clocks (5–200 MHz CMOS, 5–350 MHz SSTL/HSTL) on IN3/IN4. All references feed the same on-chip PLL, and the device automatically selects based on pin strapping or factory programming.

Does the SI5334M-B06024-GM require external configuration after power-up?

No. The SI5334M-B06024-GM is factory-programmed with a fixed configuration stored in one-time-programmable (OTP) memory. Upon power-up, it begins operation immediately in the predefined state - no I²C communication, software initialization, or external configuration is needed. This makes SI5334M-B06024-GM ideal for secure, boot-critical timing applications.

Can all four outputs of the SI5334M-B06024-GM run at different frequencies simultaneously?

Yes. Each of the four differential output pairs (CLK0A/B through CLK3A/B) is independently configurable for frequency, format, voltage, and phase. The SI5334M-B06024-GM uses four dedicated MultiSynth dividers to synthesize any frequency up to 350 MHz (or select frequencies to 710 MHz) per output - enabling true multi-frequency clock trees from a single IC.

What is the maximum output frequency supported by the SI5334M-B06024-GM in LVDS mode?

The SI5334M-B06024-GM supports LVDS outputs up to 350 MHz across the full operating temperature range (–40 to +85 °C). At higher frequencies (367–710 MHz), LVPECL is the only supported differential format - confirmed in Table 4 of the datasheet. Output drive strength and jitter remain within spec at 350 MHz LVDS with proper 100 Ω termination.

How does the SI5334M-B06024-GM handle loss-of-signal detection?

The SI5334M-B06024-GM monitors all input references and asserts the open-drain LOSLOL pin within 2.6–5 µs of signal loss on any active input. This alarm is latched until power cycle or reset, and can be used to trigger system-level failover or diagnostic logging. The SI5334M-B06024-GM also detects PLL loss-of-lock independently, with deassertion occurring within 0.01–1 µs after signal recovery.
