U2781B Frequency Synthesizer

U2781B Description

U2781B Frequency Synthesizer .
The programmable frequency synthesizer IC U2781B for µP-controlled applications is realized with Atmel Wireless & Microcontrollers’ advanced UHF proce.

U2781B Features

* D D D D D D D D D Very low current consumption (typ. 3 V/ 5 mA) Supply-voltage range: 2.7 to 5.5 V Max. input frequency: 1.1 GHz Programmable prescaler 64/ 65 or 128/ 129 Controlled by 3-wire bus with fclock up to 500 kHz Status output for PLL lock/ unlock condition Very fast phase detector SSO20 pa

U2781B Applications

* is realized with Atmel Wireless & Microcontrollers’ advanced UHF process which is very suitable for combinations of fast ECL logic and low-current I2L logic. The benefits are high input sensitivity combined with low power consumption and therefore small packages (SSO20). This makes the device a perf
