8.3.5 CDC6Cx-Q1 CISPR25 Radiated Emission Performance

The CDC6Cx-Q1 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-Q1 is configured for slow mode 2 with a 5pF termination. The test observed 1.8V and 3.3V, 25MHz CDC6Cx-Q1 oscillators in a DLY package. 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.
