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.
Features
Electrostatic sensitive device.
Observe precautions for handling.
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
Prescaler 64/65 for both inputs
SSO20 package
ESD protected according to MIL-STD 833
method 3015 cl.2
