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.
