SI5335A-B02436-GM

The SI5335A-B02436-GM is Silicon Labs’ SI5335 family device: a programmable clock generator and distribution buffer with multiple outputs. It derives several low-jitter clock signals from a single reference using an internal PLL/Digital Frequency Synthesis engine and distributes them to independent outputs. The “A” denotes a device revision, while “B02436-GM” is the packaging/date/lot code for this specific part variant.
Key points
- I2C-programmable, register-based control (use ClockBuilder Pro to generate settings)
- Multiple outputs (typically 3–4) that can be independently configured in frequency (and phase where supported)
- Fractional-N capabilities, spread-spectrum options, output enables, and configurable output levels
- Wide input reference options and low-jitter performance suitable for FPGA/SoC clocks, memory interfaces, SERDES, etc.
- RoHS-compliant package; exact package/pinout depends on the specific variant
For exact electrical specs, pinout, and packaging details, consult the SI5335 datasheet and the distributor’s product page for the SI5335A-B02436-GM.

Si5335A-B02436-GM is a four-output, programmable clock generator from Silicon Labs. Key features:

- Pin count: 24-pin package (Si5335A-B02436-GM is a 24‑lead device).
- Function: I2C-programmable clock generator / jitter-attenuating clock synthesizer with four outputs (CLK0–CLK3) for clock distribution from a reference input.

Manufacturer: Silicon Labs (Silicon Laboratories, Inc.).
What kind of company: A fabless semiconductor company that designs mixed-signal ICs (including clock generators and timing devices) and outsources fabrication to foundries.

Si5335A-B02436-GM is a multi-output, programmable clock generator and jitter attenuator. Applications include generating and distributing low-jitter reference clocks for high-speed serial interfaces (PCIe, SATA, USB, HDMI), SERDES clocks for FPGAs/ASICs, processor/memory clocks (DDR/LPDDR), network PHYs and telecom equipment, backplanes, and test/measurement gear. It derives multiple synchronized clocks from a single crystal, simplifying clock trees in data centers, storage, networking, and consumer electronics.
