Page 7: Functional Description
Philips Semiconductors 1.3GHz low voltage fractional-N synthesizer FUNCTIONAL DESCRIPTION Main Fractional-N divider The RFin inputs drive a pre-amplifier to provide the clock to the first divider stage. For single ended operation, the signal should be fed to one of the inputs while the other one is AC grounded. The pre-amplifier has a high input impedance, dominated by pin and pad capacitance. - Page 8 Philips Semiconductors 1.3GHz low voltage fractional-N synthesizer REF DIVIDER AUX/MAIN DIVIDER 1999 Nov 04 “1” “1” Figure 5.

I is the total current at pin PHP during speed up condition. PHP–SU Lock Detect The output LOCK maintains a logic ‘1’ when the auxiliary phase detector ANDed with the main phase detector indicates a lock condition.
- Page 11 Philips Semiconductors 1.3GHz low voltage fractional-N synthesizer Serial programming bus The serial input is a 3-wire input (CLOCK, STROBE, DATA) to program all counter divide ratios, fractional compensation DAC, selection and enable bits. The programming data is structured into 24 bit words; each word includes 2 or 3 address bits. Figure 8 shows the timing diagram of the serial input.
