General Description
The HMC821LP6CE is a fully functioned Fractional-N Phase-Locked-Loop (PLL) with an Integrated Voltage Controlled
Oscillator (VCO). The PLL consists of an integrated low noise VCO with a tri-band output, an autocalibration subsystem
for low voltage VCO tuning, a very low noise digital Phase Detector (PD), a precision controlled charge pump, a low
noise reference path divider and a fractional divider.
The fractional PLL features an advanced delta-sigma modulator design that allows both ultra-ne step sizes and
low spurious products. The phase detector (PD) features cycle slip prevention (CSP) technology to allow fas-
ter frequency hopping times. Ultra low in-close phase noise and low spurious also allows wider loop bandwidths for
faster frequency hopping and low micro-phonics.
For theory of operation and register map refer to the “PLLs with Integrated VCOs - RF VCOs Operating Guide”. To
view the Operating Guide, please visit www.hittite.com and choose HMC821LP6CE from the “Search by Part
Number” pull down menu.

The circuit board used in the application should use RF circuit design techniques. Signal lines should have
50 Ohm impedance while the package ground leads and exposed paddle should be connected directly
to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the
top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.

The circuit board used in the application should use RF circuit design techniques. Signal lines should have
50 Ohm impedance while the package ground leads and exposed paddle should be connected directly
to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the
top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
