Product Overview
ADF4212L is a dual frequency synthesizer that can be used to implement local oscillators (LO) in the up-conversion and down-conversion sections of wireless receivers and transmitters. It can provide the LO for both the RF and IF sections. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, programmable A and B counters, and a dual modulus prescaler (P/P + 1). The A (6bit) and B (12bit) counters, in conjunction with the dual modulus prescaler (P/P + 1), implement an N divider (N = BP + A). In addition, the 15-bit reference counter (R counter) allows selectable REFIN frequencies at the PFD input. It is widely used in application such as wireless handsets (GSM, PCS, DCS, DSC1800, CDMA, WCDMA), base stations for wireless radio (GSM, PCS, DCS, CDMA, WCDMA), wireless LANS, cable TV tuners (CATV), communications test equipment etc.
