GENERAL DESCRIPTION
The 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 (6-bit) and B (12-bit) 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. A complete phase-
locked loop (PLL) can be implemented if the synthesizer is used
with external loop filters and voltage controlled oscillators (VCOs).
Control of all the on-chip registers is via a simple 3-wire
interface with 1.8 V compatibility. The devices operate with a
power supply ranging from 2.7 V to 3.3 V and can be powered
down when not in use.
