概述

Description

SI5324E-C-GMR is Silicon Labs’ I2C‑programmable clock generator/jitter cleaner. It takes a reference clock (or two) and generates multiple low‑jitter output clocks with configurable frequencies, formats, and phase relationships. Key points:
- Up to four outputs (configurable per application) in LVDS/LVPECL/CMOS formats.
- Internal PLL/clocking engine to clean jitter and synthesize required frequencies.
- Programmable via I2C; supports power‑on reset, software reset, output enable, and optional holdover.
- Features like spread‑spectrum modulation for EMI reduction.
- Useful for SERDES, memory interfaces, PHYs, and other subsystems needing multiple synchronized clocks from a single reference.
- E‑C‑GMR denotes a specific variant: E = industrial temperature range, C = package/pinout variant, GMR = package/reel code.
In short, it’s a versatile, multi‑output clock source that gives you clean, synchronized clocks from one reference for complex digital systems.

Features

SI5324E-C-GMR is a high-performance, quad clock generator/buffer with I2C control. Key features:
- Four independent outputs with selectable signaling standards (LVDS/LVPECL/HCSL/CMOS) and adjustable drive strength; outputs can be individually enabled/disabled.
- On-chip PLL and zero-delay buffering for low skew clock distribution.
- I2C/SMBus control to program output frequencies/dividers, reset, and SSC (Spread Spectrum Clocking) options.
- Wide reference input domain (crystal/oscillator) with fast-lock and jitter-tolerant operation.
- Spread Spectrum Clocking to reduce EMI; supports synchronization across outputs.
- Low jitter and stable operation suitable for high-speed SERDES, memory interfaces, FPGA, PCIe, etc.
- Power: 3.3 V supply (I/O compatible with 1.8–3.3 V); industrial temperature range (-40 to 85 C).
- Package: compact GMR (20-pin QFN) for easy integration.
Note: exact frequency ranges, input/output voltage levels, and drive options are configured via the I2C interface per the datasheet.

Package

Package type: QFN-32 (32-pin) with exposed pad, 6x6 mm footprint (GMR variant).

Pinout

- Pin count: 24 pins (QFN/GMR package)
- Function: Quad-output clock generator and jitter cleaner. It takes a reference clock and synthesizes four low-skew output clocks; programmable via a serial interface (I2C) for divide/multiply settings.

Manufacturer

- Manufacturer: Silicon Labs (Silicon Laboratories, Inc.)
- What kind of company: A U.S.-based fabless semiconductor company that designs and sells silicon, software, and system-level solutions (including timing ICs, microcontrollers, and wireless transceivers) for IoT, automotive, and other markets.

Application

Si5324E-C-GMR is a high‑performance jitter‑attenuating clock generator/multiplier with multiple outputs. Applications include:
- High‑speed SerDes clock generation/distribution (PCIe, SATA/SAS, USB 3.x, Ethernet)
- Telecom/network equipment (line cards, OLT/ONU, fiber transceivers)
- Data‑center backplanes
- Optical transceivers (SFP+/SFP28)
- Any system needing low‑jitter, multi‑output reference clocks from a single source
