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
