ML12034

2.0 GHz Dual Modulus

Prescaler

MECL PLL COMPONENTS ÷32/33, ÷64/65 DUAL MODULUS PRESCALER

SEMICONDUCTOR TECHNICAL DATA

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

• Supply Voltage 4.5 to 5.5 V

• ML12034 for Positive EdgeTriggered Synthesizers

• 12mA Maximum, –40 to 85°C, V = 5.5 Vdc

• Modulus Control Input is Compatible with

Standard CMOS and TTL

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

becomes available, will be identified by a part

number prefix change from ML to MLE.

• Low–Supply Current 8.5 mA Typical

• Operating Temperature Range T = –40 to 85°C
