BU2630
BU2630 is Dual PLL frequency synthesizer manufactured by ROHM.
Description of data (1) Programmable divider data: D0 X D15
(2) Reference frequency data: R0 X R13
(3) Output port control data : P-T (P-R) TON (RON) 1 : Open drain output ON (LO) 0 : Open drain output OFF (HI) (4) OFF transmission side (reception side) : Operation stopped F
- T (F
- R) pull-down : TPD (RPD) high-impedance, LD = OFF (5) PS Programmable device change : No. of divisions = 3 X 4095
96 munication ICs
