ML145145
4鈥揃it Data Bus Input PLL
Frequency Synthesizer
INTERFACES WITH SINGLE鈥揗ODULUS PRESCALERS
Legacy Device:
Motorola MC145145-2
The ML145145 is programmed by a 4鈥揵it input, with
strobe and address lines. The device features consist of a
reference oscillator, 12鈥揵it programmable reference
divider, digital phase detector, 14鈥揵it programmable
divide鈥揵y鈥揘 counter, and the necessary latch circuitry for
accepting the 4鈥揵it input data.
鈥?Operating Temperature Range: TA 鈥?40 to 85擄C
鈥?Low Power Consumption Through the Use of CMOS
Technology
鈥?3.0 to 9.0 V Supply Range
鈥?Single Modulus 4鈥揃it Data Bus Programming
鈥?梅N Range = 3 to 16,383, 梅R Range = 3 to 4,095
鈥?鈥淟inearized鈥?Digital Phase Detector Enhances
Transfer Function Linearity
鈥?Two Error Signal Options:
Single鈥揈nded (Three鈥揝tate)
Double鈥揈nded
