Description

The SI5324E-C-GMR is a four‑output, programmable clock generator/jitter cleaner in the Silicon Labs/IDT family. It takes a reference clock and produces four synchronized output clocks, suitable for distributing timing to FPGAs, SERDES, memory interfaces, and network PHYs. It uses a serial interface to program frequency synthesis, output enable, and other options, providing tight phase relationships and low jitter.
Key points:
- 4 outputs with programmable division/multiplication from a single reference
- I2C‑style serial interface for configuration
- Programmable output formats and duty cycle; enable/holdover features
- Jitter cleaning and deterministic timing for multiple domains
- Designed for extended/industrial operating ranges in a small package (GMR)
Typical uses include FPGA clocking, PCIe/SERDES reference clocks, Ethernet/SATA PHY timing, and memory interface clocks.

Equivalent

Direct one-to-one drop-in equivalents for the SI5324E-C-GMR do not exist due to packaging and feature differences. Closest alternatives by function:
- Silicon Labs: SI5320, SI5322, SI5344 (multi-output jitter-cleaning clock generators)
- Analog Devices: AD9523-1 / AD9528 (multi-output clock distribution with jitter reduction)
- Renesas/IDT: 8T49N family clock generators (e.g., 8T49N24/8T49N27)
- Microchip/MaxLinear: LMK03000 family (multi-output clock generators)
- TI: CDCE-series clock distribution/synthesizers (e.g., CDCE72010)
Check datasheets for exact specs.

Here are the core features of SI5324E-C-GMR:
- High-performance jitter-cleaning clock generator and distributor
- One reference input, up to four independently programmable outputs
- Fractional-N PLL with adjustable multiply/divide per output
- Spread Spectrum Clocking (SSC) with programmable depth and rate
- Multiple output formats: LVPECL, LVDS, and LVCMOS with selectable drive strength and common-mode
- I2C/SMBus serial control for programming, monitoring, and power management
- Power-down/low-power modes and optional holdover behavior
