Not sure Jose. Have you looked with a scope at the output of the Si570?

Tony,
Do not not yet if my case belongs to that category...

Good Morning All,
I have a CMOS Si570 mounted on a Lite+Xtall board and am obderving
strange behavior of the RF output of the device.
The RF output is on for about 4msec, goes off for about 2msec, and
continues to repeat this on-off pattern continuously. The frequency of
the RF output is about 50MHz during the on time. The RF output
envelope displays sudden transitions from on to off or off to on. The
PIC on the board acts as if I2C communications is proceeding normally
with each DIP switch input change but results in no change in the RF
output of the Si570.
Has anyone observed proper operation of the CMOS Si570 devices I have
been filling orders with in recent weeks? Also, has anyone else
observed faulty operation of a CMOS Si570 device?
Thanks and 73,
