GENERAL DESCRIPTION
The ADF4217L/ADF4218L/ADF4219L are low power dual
frequency synthesizers that can be used to implement local
oscillators in the up-conversion and down-conversion sections
of wireless receivers and transmitters. They can provide the LO
for both the RF and IF sections. They consist 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 prescaler (P/P + 1). The A and B counters,
in conjunction with the dual modulus prescaler (P/P + 1),
implement an N divider (N = BP + A). In addition, the 14-bit
reference counter (R Counter) allows selectable REFIN fre-
quencies at the PFD input. A complete PLL (phase-locked
loop) can be implemented if the synthesizers are used with an
external loop filter and VCOs (voltage controlled oscillators).
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 2.6 V to 3.3 V and can be powered down when
not in use.
