Zigbee: 13192 PLL lock?

bshaw — Mon, 07 Aug 2006 23:13:52 GMT

What causes a lost lock interrupt on a MC13192? The manual states that it can happen but does not state what causes it or what to do to fix it. I'm getting this interrupt constantly while trying to do a CCA.

I'm using SMAC 4.0 on a mc9s08gt60 to talk to the mc13192. I'm getting through the '192 register initialization OK and reading back sane values from the '192. As soon as I try my first CCA I get the lost PLL lock interrupt.

Any thoughts would be appreciated, I'm stuck here.

Best,

Bill

Hi Bill,

Is this your own hardware or a Freescale development board? Undoubtedly, the cause of the PLL losing lock is noise upsetting it.

Give us some more details, and we'll try to help.

I always get this when the PHY layer interface is not correctly assigned...

I.E. wrong library or wrong definitions for Xcvr interface on custom hardware... see "App_Target.h" and "Target.h"
