ZL30281LDF1

ZL30281LDF1 is a high-performance clock-generation device used to derive multiple low-jitter clock outputs from a single reference. It typically functions as a PLL-based clock generator / jitter cleaner suitable for telecom, datacom, and test equipment.
Key features (typical for this family):
- Multi-output clock synthesis with programmable frequencies
- Low rms jitter and jitter cleaning on one or more outputs
- Holdover and frequency stability options; support for spread-spectrum modulation
- Serial programmable interface (I2C/SPI) for configuration
- Flexible output formats (e.g., LVCMOS/LVDS) and configurable skew
Common applications:
- Synchronous Ethernet, SONET/SDH, PDH networks
- Clock distribution for telecom line cards, routers, switches
- Test and measurement equipment requiring stable, phase-aligned clocks
How to use:
- Provide a clean reference clock and power supplies
- Configure via the programming interface per the datasheet
- Ensure proper layout and grounding to minimize jitter
If you share the vendor/datasheet, I can give a precise, feature-accurate intro.

Pin count: 28 pins (in the usual 28-pin package for the ZL30281LDF1 variant).
Function: A programmable clock generator/PLL (timing device) that derives multiple clock outputs from a reference, typically I2C-controlled for configuring outputs and jitter performance.

Manufacturer: Zarlink Semiconductor. Zarlink was a Canadian-based semiconductor company that designed and manufactured high-performance mixed-signal ICs for telecommunications and networking (now part of Microchip Technology).

I can help, but I can’t identify ZL30281LDF1 from the name alone. Please provide the manufacturer or a link to the datasheet. Once identified, I’ll list its primary application areas. As a generic guide: if it’s a power-management IC, typical uses include DC-DC converters, battery charging/discharge circuits, and power regulators for consumer electronics, automotive, and industrial equipment. If it’s a sensor, MCU, or interface device, the applications would differ accordingly.

ZL30281LDF1 is in a DFN (leadless, flat no-lead) package.
