I 2 C Bit Description
MAX2140 Programming Bits:
The MAX2140 conforms to the Philips I 2 C standard,
400kbps (fast mode), and operates as a slave.
The MAX2140 addresses can be selected from three
values, which are determined by the logic state of the
two address-select pins I 2 CA1 and I 2 CA2. In all cases,
the MSB is transmitted (and read) first.
MAX2140 I 2 C-Compatible Programming Bit Definition:
BYTE PLLint:
RFD = reference buffer division: RFD = 0 (/1) and
RFD = 1 (/2)
N6 to N0 is the binary-written main dividing ratio,
integer part.
BYTE PLLfrac2:
PLS = Reserved: use only PLS = 0
LI1/0 = Reserved: use only LI1 = LI0 = 0
INT = Integer N mode: INT = 1 (fractional) and INT =
0 (integer)
