Cycle slip reduction for faster lock times

The ADF4157 is a 6 GHz fractional-N frequency synthesizer

with a 25-bit fixed modulus, allowing subhertz frequency

resolution at 6 GHz. It consists of a low noise digital phase

frequency detector (PFD), a precision charge pump, and

a programmable reference divider. There is a Σ-Δ based

fractional interpolator to allow programmable fractional-N

division. The INT and FRAC registers define an overall

N divider, N = INT + (FRAC/2²⁵). The ADF4157 features cycle

slip reduction circuitry, which leads to faster lock times without

the need for modifications to the loop filter.

Control of all on-chip registers is via a simple 3-wire interface.

The device operates with a power supply ranging from

2.7 V to 3.3 V and can be powered down when not in use.
