U2784B

2200 MHz / 200 MHz Twin PLL

Description

U2784B is a low power twin PLL manufactured with It features a wide supply voltage range from 2.7 to 5.5 V.

TEMIC’s advanced UHF process. The maximum operat- Prescaler and power down function for both PLL’s is inte-

ing frequency is 2200 MHz and 200 MHz respec tively. grated. Applications are DECT, DCS 1800 and WLAN.

Features

Benefits

Low current consumption leads to extended talk time

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

Twin PLL saves costs and space

Supply voltage range 2.7 to 5.5 V

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

in time

Maximum input frequency PLL1: 2200 MHz,

PLL2: 200 MHz

2 pins for separate power down functions

Output for PLL lock status

Prescaler 64/65 for PLL1 and 8/9 for PLL2

SSO-20 package

ESD protected according to MIL-STD 833
