each recommendation contained in
To ensure proper operation of the CX25870/871, the designer must adhere to
A 0-10 ohm resistor between COMP and 0.1 !F capacitor (which is connected to VAA)
was originally recommended for Bt868/9-designs.
The 0-10 ohm resistor placed between the 0.1 !F cap and the COMP pin was
recommended to better tune the COMP circuit to prevent an internal op-amp from
oscillating. Based on the Bt868/9's DAC performance over time and the CX25870/1's
continued usage of these same DACs, this resistor was deemed to not be necessary
and should be removed for all CX25870/1 designs.
Capacitor from VREF to GND must be 1.0 !F for the CX25870/1. Capacitor from VREF
to GND must be 0.1 !F for the Bt868/9.
RSET, the resistor from FSADJUST pin to GND, must be 75 ", +/- 1% for all
CX25870/1-based designs.
RSET must be 100 ohm, +/- 1% for all Bt868/9-based designs.
