MB88155
■ PRODUCT LINEUP
The MB88155 is available in different models : 2 models different in multiplier ( × 1 and × 4) , 2 in modulation
type (center-spreading and down-spreading) , 2 in input frequency range at a multiplier of 1 (12.5 MHz to
25 MHz and 25 MHz to 50 MHz) , and 1 in input frequency range at a multiplier of 4 (12.5 MHz to 20 MHz) .
The MB88155 is also available in two versions : modulation-on/off selectable version (with ENS pin) and power-
down function built-in version (with XPD pin) .
