pF

(1)

Verified with crystals specified for a load capacitance of CL = 8 pF, the PCB related capacitive load was estimated to be 2.3 pF, and

completed with a load capacitors of 4 pF on each crystal pin connected to GND. XTALs tested: NX3225GA 10MHz EXS00A-CG02813

CRG, NX3225GA 19.44MHz EXS00A-CG02810 CRG, NX3225GA 25MHz EXS00A-CG02811 CRG, and NX3225GA 30.72MHz

EXS00A-CG02812 CRG.

(2)

For 30.73 MHz to 50 MHz, TI recommends to verify sufficient negative resistance and initial frequency accuracy with the crystal vendor.

The 50-MHz use case was verified with a NX3225GA 50MHz EXS00A-CG02814 CRG. To meet a minimum frequency error, the best

choice of the XTAL was one with CL = 7 pF instead of CL = 8 pF.

(3)

With NX3225GA_10M the measured remaining negative resistance on the EVM is 6430 Ω (43 x margin)

(4)

With NX3225GA_25M the measured remaining negative resistance on the EVM is 1740 Ω (25 x margin)

(5)

With NX3225GA_50M the measured remaining negative resistance on the EVM is 350 Ω (11 x margin)

(6)

Maximum drive level measured was 145 µW; XTAL should at least tolerate 200 µW
