简  介:U2784B 2200 MHz / 200 MHz Twin PLL Description U2784B is a low power twin PLL manufactured with TEMIC’s advanced UHF process. The maximum operating frequency is 2200 MHz and 200 MHz respec tively. It features a wide supply voltage range from 2.7 to 5.5 V. Prescaler and power down function for both PLL’s is integrated. Applications are DECT, DCS 1800 and WLAN. Features D Very low current consumption (typical 3 V/12 mA) D Supply voltage range 2.7 to 5.5 V D Maximum input frequency PLL1: 2200 MHz, PLL2: 200 MHz Benefits D Low current consumption leads to extended talk time D Twin PLL saves costs and space D One foot print for all TEMIC twin PLL’s saves designin time D 2 pins for separate power down functions D Output for PLL lock status D Prescaler 64/65 for PLL1 and 8/9 for PLL2 D SSO-20 package D ESD protected according to MIL-STD 833 method 3015 cl. 2 Block Diagram 1 VS analog VS digital DGND AGND OSCi OSCo 4 2 6 15 7 8 Oscillator Control functions 16 bit latch Lock select 10 Lock Port2 Ports Power down Test 9 14 20 5I/Port 0 HPD1/Port1 HPD2/Port4 Port3 on / off divide by 2 12 bit latch 1 12 bit reference divider 1 17 bit latch 1 Phase detector 1 Charge pump 1 3 17 CP1 VScp RFi1 5 64 / 65 Prescaler 1 17 bit main divider 1 Clock Data Enable 11 3 bit 12 13 Load control 17 bit Shift register Pump bias 19 Iset 12 bit latch 2 12 bit reference divider 2 14 bit latch 2 Phase detector 2 Charge pump 2 18 CP2 RFi2 16 8 / 9 Prescaler 2 14 bit main divider 2 95 10611……
