mc1451452 motorola 1
! interfaces with singlemodulus prescalers the mc1451452 is programmed by a 4bit input, with strobe and address lines. the device features consist of a reference oscillator, 12bit program- mable reference divider, digital phase detector, 14bit programmable divide byn counter, and the necessary latch circuitry for accepting the 4bit input data. ? operating temperature range: 40 to 85 c ? low power consumption through the use of cmos technology ? 3.0 to 9.0 v supply range ? single modulus 4bit data bus programming ? n range = 3 to 16,383, r range = 3 to 4,095 ? alinearizedo digital phase detector enhances transfer function linearity ? two error signal options: singleended (threestate) doubleended not recommended for new designs; product to be phased out. closest equivalents are the mc1451512, mc1451701, mc14519x series, and mc14520x series. block diagram f v ld st a2 a1 a0 d3 d2 d1 d0 lock detect phase detector b phase detector a 12bit r counter latches latch control circuitry 14bit n counter latch 1 latch 2 l3 ref out osc in osc out f in pd out f r latch 4 latch 5 latch 6 f r f v latch 0 order this document by mc1451452/d
