Perceptia Updates Design Kit for pPLL03 on GlobalFoundries 22FDX Platform

Nov. 06, 2025 – 

Sydney, Australia  — Perceptia Devices, a leader in high-performance clocking IP, today announced the availability of an updated design kit for its pPLL03 phase-locked loop IP on GlobalFoundries’ 22FDX® (22nm FD-SOI) technology node.

The pPLL03 is Perceptia’s low jitter, high-performance PLL IP core targeted at demanding SoC applications including AI accelerators, microprocessors, ADC/DAC sampling clocks, and high-speed digital subsystems. The release of the design kit enables SoC developers to efficiently incorporate the pPLL03 into their designs with full support for layout, simulation, and timing closure.

This update upgrades pPLL03 to include a power conditioning circuit that makes it more tolerant to power supply noise and allows pPLL03 to be more reliable in a range of environments.

Key technical features of the pPLL03 include:

• Output frequency range: Up to 4 GHz, supporting integer and fractional-N operation
• Peak Period Jitter: Less than 2.1% of a cycle at 4GHz (5.25ps)
• Fast lock time (400 reference clock cycles)
• Fractional output division for rapid frequency change with glitch-less transition and 6 bit fractional resolution suitable for dynamic frequency scaling
• Compact footprint: Highly area-efficient implementation with minimal analog overhead.
  • 0.008 sq mm in GF 22FDX
• Robust behaviour across process, voltage, and temperature extremes

The pPLL03 supports both integer-N and fractional-N synthesis, allowing for fine-grained frequency generation. Its all-digital control interface enables easy integration with standard digital flows and software-driven configuration.

“Our goal with pPLL03 was to deliver best-in-class jitter performance with integration flexibility in advanced nodes like GlobalFoundries 22FDX,” said Julian Jenkins, CTO at Perceptia. “The silicon data validates our design and methodology, and the IP is production-ready.”

GlobalFoundries’s 22FDX platform is tailored for low-power, high-density applications such as mobile, edge AI, RF connectivity, and embedded processing. The availability of pPLL03 in this process gives customers a differentiated clocking solution optimised for FD-SOI characteristics.

The pPLL03 design kit includes:

• Liberty (.lib) timing models
• Verilog and Verilog-A simulation models
• GDSII and LEF physical views
• CDL netlist
• Integration guidelines and layout constraints
• Comprehensive verification and characterisation data

The kit is available immediately to qualified licensees.
