0XOWLIXQFWLRQ 2XWSXW for the signals IRN, ΦV, ΦVN and port 1.
0XOWLIXQFWLRQ ,23LQ for the output signals IVN, ΦRN and the
input signal ,REF.
– The signals ΦR and ΦV are the digital output signals of the
phase and frequency detector for use in external active
current sources (see phase detector output wave forms).
– The signals IRN and IVN are the scaled down signals of the
reference frequency and VCO-frequency. The L-time
corresponds to 1/IRI and 1/IFI respectively.
– In the port function the port 1 output signal is assigned to the
information of the status program. The output switches with
the rising edge of the
EN-signal. The standby mode does not affect the port
function.
– In the internal charge pump mode the input signal ,REF
determines the value of the PD-output current.
Reference current for charge pump:
,REF = (9DD – 9REF)/R1
= 100µA (tolerance of ±20% or less is recommended)
R1:see application circuit
9REF:see AC/DC characteristics
