HMC832 datasheet


The HMC832 is a 3.3 V, high performance, wideband, fractional-N, phase-locked loop (PLL) that features an integrated voltage controlled oscillator (VCO) with a fundamental frequency of 1500 MHz to 3000 MHz, and an integrated VCO output divider (divide by 1/2/4/6/…60/62), that enables the HMC832 to generate continuous frequencies from 25 MHz to 3000 MHz. The integrated phase detector (PD) and delta-sigma (Δ-Σ) modulator, capable of operating at up to 100 MHz, permit wider loop bandwidths and faster frequency tuning with excellent spectral performance.



1. RF bandwidth : 25 MHz to 3000 MHz

VCA3 Datasheet PDF – Crystal Oscillator – Vectron

Part Number: VCA3

Function: 3.3, 5.0 volt CMOS Oscillator

Package: PCB 4 Pin Type

Manufacturer: Vectron International

Image :


This is Crystal Oscillator. Vectron’s VCA3 Crystal Oscillator (XO) is quartz stabilized square wave generator with a  CMOS output, operating off  a 3.3 or 5.0  volt supply.

The VCA3 uses fundamental or  3rd overtone crystals, for output frequencies <  80MHz, resulting in low jitter performance , typically 0.5ps rms in the  12 kHz to 20MHz band.


1. CMOS output

2. Output frequencies to  160MHz

3. Tri-stateoutput for  board test and debug

4. 0/70 or  –40/85 °C operating temperature
