Note 1: Limits are guaranteed by 100% testing, sampling, or correlation with worst case test conditions.

Note 2: qJA is measured with the component mounted on the Evaluation PCB in free air.

Note 3: Phase noise and lock up time tested with 1LO VCO Q = 10, kVCO = 100MHz/V. Phase noise measured at IF output by down converting a 2450MHz signal to a

260MHz IF. Input signal at –20dBm. Charge pump current set to default.

Note 4: Measurements taken with 236MHz 2LO. Tank circuit of 2LO VCO Q = 8, kVCO = 40MHz/V.Charge pump current set to maximum.

Note 5: This is proven by design, it is not tested in production.

Note 6: Measured with an external Transmit VCO, with Q = 15, kVCO = 120MHz/V, output power 0dBm, –10dBm input to TS272. Reference signal is a 260MHz sine

wave.

Note 7: Measured with an external Transmit VCO, with Q = 15, kVCO = 120MHz/V, output power 0dBm, –10dBm input to TS272. Reference is a 260MHz center

frequency signal, modulated with 4GFSK. Error is measured relative to the reference signal at the center of the data symbol.
