Notes
1. Measured and guaranteed only on the Philips evaluation board, including Printed-Circuit Board (PCB) and balun filter
with internal slicer.
2. Mean of the values of transmit frequency at VCP/VCOtune = 0.3 and 2.7 V.
3. Measured with VCP/VCOtune = 1.5 V, mean of the values of transmit frequency at VMOD = 0 and 0.5 V.
4. Frequency difference measured during 420 µs with VMOD = 0 (no modulation applied), at least 20 µs after disabling
the synthesizer.
5. Except for three occurrences, as defined in the DECT specification.
6. VIH should never exceed 3.6 V.
