ML12034

2.0 GHz Dual Modulus

Prescaler

Legacy Device: Motorola MC12034A

The ML12034 can be used with CMOS synthesizers requiring

positive edges to trigger internal counters such as Motorola’s

MC145xxx series or Lansdale’s ML145xxx series in a PLL to pro-

vide tuning signals up to 2.0 GHz in programmable frequency steps.

A Divide Ratio Control (SW) permits selection of a 32/33 or

64/65 divide ratio as desired.

The Modulus Control (MC) selects the proper divide number

after SW has been biased to select the desired divide ratio.

• 2.0 GHz Toggle Frequency

Note: Lansdale lead free (Pb) product, as it

becomes available, will be identified by a part

number prefix change from

ML to MLE.
