| ML12509 ML12511 ML12513 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 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. 16 1 CERDIP 16 = E CERAMIC PACKAGE CASE 620 CROSS REFERENCE/ORDERING INFORMATION PACKAGE MOTOROLA LANSDALE CERDIP 16 CERDIP 16 CERDIP 16 12509/BEA 12511/BEA 12513/BEA ML12509/BEA ML12511/BEA ML12513/BEA PIN CONNECTIONS VCCO Q Q (-) (+) MTTL VCC MTTL Output VEE 1 2 3 4 5 6 7 8 (Top View) 16 VCC 15 Clock 14 VBB 13 E1 MECL 12 E2 MECL 11 E3 MECL 10 E4 MECL 9 E5 MECL MAXIMUM RATINGS Characteristic Symbol Rating Unit (Ratings above which device life may be impaired) Power Supply Voltage (VCC = 0) Input Voltage (VCC = 0) Output Source Current Continuous Surge Storage Temperature Range VEE Vin IO 50 100 Tstg -65 to 175 C -8.0 0 to VEE Vdc Vdc mAdc (Recommended Maximum Ratings above which performance may be degraded) Operating Temperature Range DC Fan-Out (Note 1) (Gates and Flip-Flops) TA n -55 to 125 70 C -- NOTES: 1.

Test outputs of the device must be tested by sequencing through the truth table. All input, power supply and ground voltages must be maintained between tests. The clock input is the waveform shown. 2. In addition to meeting the output levels specified, the device must divide by 5 or 8 during this test. The clock input is the waveform shown. 3. In addition to meeting the output levels specified, the device must divide by 6 or 9 during this test. The clock input is the waveform shown. Clock Input VIHmax VILmin Each MECL 10,000 series circuit has been designed to meet the dc specifications shown in the test table, after thermal equilibrium has been established. The circuit is in a test socket or mounted on a printed circuit board and transverse air flow greater than 500 linear fpm is maintained. Outputs are terminated through a 50 resistor to -2.0 V. Test procedures are shown for only one gate. The other gates are tested in the same manner. Page 6 of 12 www.lansdale.com Issue 0 ML12509, ML12511, ML12513 LANSDALE Semiconductor, Inc. Figure 3.
