Clock generator 32kHz

Hello,
I need clock generator 32kHz (square 3,3V) for CPLD. Does anyboby know a suitable chip (as small as possible). Thanks.

Why dont you use a 32khz crystal oscillator ? it is simple and cheap .
 

I vote use a 32Khz cristal, remember, to drive it, you will need schotkly CMOS or input with high impedance gates, maybe you need to use an external standard CD40xx series to make the 32Khz oscilator.

Other solution if you have a CPLD, and other highter clock, you can divide the highter clock to obtain 32.768Khz
 

Hello,
MAXIM semiconductor have DS32K. It gives a 32768 Hz signal, and it's temperature compensed.
