MECL PLL Components

Dual Modulus Prescaler

Legacy Device:

Motorola 12509, 12511, 12513

These devices are two–modulus prescalers which will divide by

5 and 6, 8 and 9, respectively. A MECL–to–MTTL translator is

provided to interface directly with the Motorola MC12014

Counter Control Logic. In addition, there is a buffered clock input

and MECL bias voltage source.

• ML12509 480 MHz (÷5/6), ML12511 550 MHz (÷8/9),

ML12513 550 MHz (÷10/11)

• MECL to MTTL Translator on Chip

• MECL and MTTL Enable Inputs

• 5.0 or –5.2 V Operation*

• Buffered Clock Input — Series Input RC Typ, 20

Ω

and 4.0 pF

• VBB Reference Voltage

• 310 mW (Typ)

* When using a 5.0 V supply, apply 5.0 V to Pin 1 (VCCO),

Pin 6 (MTTL VCC), Pin 16 (VCC), and ground Pin 8

(VEE). When using –5.2 V supply, ground Pin 1 (VCCO),

Pin 6 (MTTL VCC), and Pin 16 (VCC) and apply –5.2 V to

Pin 8 (VEE). If the translator is not required, Pin 6 may be

left open to conserve DC power drain.
