8.3.5 CDC6Cx CISPR25 Radiated Emission Performance

The CDC6Cx radiated EMI emissions performance passed up to CISPR-25 Class 5 for all bands except GPS L1 (1567.42MHz to 1583.42MHz) where the device passes Class 3. The CDC6Cx is configured for slow mode 2 with a 5pF termination. The test observed 1.8V and 3.3V, 25MHz CDC6Cx oscillators in the DLE and DLY packages. The boards used have 50mil trace lengths, and the boards are tested in Texas Instruments’ pre-compliant EMI chamber set up for CISPR-25 with antennas operating up to 13GHz.
