I’m referring to the nRF54L15 Product Specification, document 4503_018 v1.0:
Section 10.3.1, “Circuit configuration 1 for QFN48 (QFAA),” starts on page 889.
Figure 180, the circuit schematic, appears on page 890.
Table 87, “Bill of material for circuit configuration 1,” appears on page 891.
Table 87 specifies C6 as 1.5 pF ±0.05 pF and C9 as 2.0 pF ±0.05 pF. These tolerances significantly restrict sourcing compared with readily stocked ±0.1 pF parts.
What measured performance difference drove these requirements? Specifically, what degradation should we expect with ±0.1 pF capacitors?
Are these tolerances essential to meeting the published radio specifications, or do they reflect the particular components Nordic validated? Guidance on acceptable tolerances would help avoid unnecessary sourcing constraints.
