RADIO CONTROLLED RECEIVER IC D6002
DESCRIPTION
Out li ne Dra wi ng
The D6002 i s a bi pola r integrate d straight
through rec eiver c ircuit in the frequency range
from 40kHz up t o 200kHz wit h ASK modula tion.
The IC rece ivers and demodul at es ti me code
signals transmi tt ed by DCF77,M SF , WWVB
and G2AS.
The devi ces is designed for radi o c ontrolle d
cl oc k a ppli cat ions wi th very hi gh sensi tivi ty.
Int egrated funct ions as s tand by mode and
compl ementa ry out put st age s offer fe atures for
uni ve rsa l appli cat ions.
The BIP2 te chnology makes al l the above feat ures possible for ve ry l ow cost
applic ati ons.
FEATURE
Single chi p strai ght through rece ive r.
Low power ba tt ery a ppli cati ons(1. 1~ 3.6V)
Very low power c onsumpti on.
Powe r down modus.
Wi de fre quency range (40~ 200kHz )
Very high se nsi ti vi ty.
High sel ecti vi ty by qua rt z re sonator.
Comple menta ry output sta ge s.
M inimum exte rnal compone nt s.
APPLICATIONS
Re cei ve r for t ime c ode t rans mit te r signal's
Re cei ver for ASK modul ate d dat e si gnal 's.

APPLICATION HINT'S
The PC B has to be desi gned for RF condit ions.
The fe rrit e a nt enna is a crit ica l devi ce s of t he c ompl et e c lock recei ve r.
The di me nsi oning of the antenna resonant resi sta nce is a compromi se be twee n hi gh
si gnal vol tage and low antenna noi se volt age . The Q-fac tor of antenna should be hi gh
for a tt enuat ion of infe rence signal's. In t he appl ic ati on circui t i s t he Rref 100k,
Q=80.
To achieve a hi gh sel ect ivit y the parasit ic paral lel capacit ance of the crysta l should be
1~1.5pF.
For a t roubl e-free re cepti on the ca pac it or on GND and CD3 have t o be arranged nearby
the chi p foot prints.
