Absolute Maximum Ratings
Note:
1. Absolute maximum ratings are those beyond which operation and reliability of the device cannot be guaranteed. Subjecting
devices to these limits for extended periods of time may result in actual failure of the device.
Operating Conditions

Offset adjust input pin effectively corrects quadrature phase error. A 20K
W
variable resistor to ground can cover the range of correction.
Resistor at this pin sets the dominant filter cut-off frequency for the filter
internal to the chip between IMX
±
and IDAT pins. A 4K
W
at this pin gives a
3dB point of 8.3MHz.
This digital input should be LOW during normal operation. A TTL/CMOS high
input on this pin shuts down all the oscillators
This voltage output can be used to gain control the tuner front-end.
