MAX7042 RX center frequency tuning

Category: Datasheet/Specs
Product Number: MAX7042ATJ+

Hi all,

The MAX7042 can be tuned to one of four frequencies using the 2 frequency-select bits FSEL1 and FSEL2:308, 315, 418, and 433.92MHz.

Is it possible to use the RX center frequency with the following frequency combinations ?

Is there something wrong with the internal circuitry?

RX:312.5 MHz , xtal REF:9.43125 MHz , LO:301.8 MHz(9.43125*32) , IF:10.7 MHz

and select L2 and C9 of the LC tank filter to resonate at the RF input frequency,312.5 MHz.

Best regards,
