U2782B  
1100 MHz Twin PLL  
Description  
The IC U2782B is a low power twin PLL manufactured  
with TEMIC’s advanced UHF process. The maximum  
operating frequency is 1100 MHz for both PLLs.  
It features a wide supply voltage range from 2.7 to 5.5 V.  
Prescaler 64/65 and power down function for both PLL’s  
is integrated. Applications are CT1, IS54, JDC etc.  
Electrostatic sensitive device.  
Observe precautions for handling.  
Features  
Benefits  
Low current consumption leads to extended talk time  
Very low current consumption (typical 3 V/11 mA)  
Supply voltage range 2.7 to 5.5 V  
Maximum input frequency: 1100 for both PLLs  
2 pins for separate power down functions  
Output for PLL lock status  
Twin PLL saves costs and space  
One foot print for all TEMIC twin PLL’s saves design-  
in time  
Prescaler 64/65 for both inputs  
SSO20 package  
ESD protected according to MIL-STD 833  
method 3015 cl.2
