U2789B-AFS

2000 MHz / 200 MHz Twin PLL

Description

U2789B is a low power twin PLL manufactured with 5.5 V. Prescaler and power down function for both PLL’s

TEMIC’s advanced UHF process. The maximum is integrated. Applications are wireless telephones, e.g.

operating frequency is 2000 MHz and 200 MHz respec- DECT phones.

tively. It features a wide supply voltage range from 2.7 to

Features

Benefits

Very low current consumption (typical 3 V/12 mA)

Low current consumption leads to extended talk time

Supply voltage range 2.7 V – 5.5 V

Twin PLL saves costs and space

Maximum input frequency PLL1: 2000 MHz,

PLL2: 200 MHz

One foot print for all TEMIC twin PLL’s saves design-

in time

2 pins for separate power down functions

Output for PLL lock status

Prescaler 32/33 for PLL1 and 8/9 for PLL2

SSO20 package

ESD protected according to MIL-STD 833
