Dual Power PLL Frequency Synthesizer

The ADF4212L is a dual Frequency Synthesizer that CAN be us to implement local Oscillators (LO) in the up-conversion and down-conversion sections of Wireless receivers and transmitter It CAN provide the LO for both the RF and IF sections. It con- sists of a low noise digital PFD (Phase Frequency Detector), a precision Charge Pump a programmable reference divider, programmable A and B Counters and a dual modulus prescale (P/P + 1). The A (6-bit) and B (12-bit) Counters in conjuncti with the dual modulus prescaler (P/P + 1), implement an N divider (N = BP + A). In addition, the 14-bit reference counte (R counter) allows selectable REFIN frequencies at the PF input. A complete PLL (Phase-Locked Loop) CAN be implemente if the synthesizer is used with external loop Filters and VCOs (Voltage Controlled Oscillators). Control of all the on-chip Registers is via a simple 3-wire inter- face with 1.8 V compatibility. The devices operate with a pow supply ranging from 2.7 V to 3.3 V and CAN be powered down when not in use. By Analog Devices, Inc.
