PFD1K

8 GHz Phase Frequency Detector IC

with Dual 40 GHz Prescalers

Description

The PFD1K is a high frequency phase fre-

quency detector with fully differential inputs

and outputs. It features dual 7 bit programma-

ble high speed prescalers which allow the

PFD1K to operate up to 40 GHz for the refer-

ence and voltage controlled oscillator input fre-

quency. The 8 GHz phase-frequency detector

allows operation at higher reference frequen-

cies with concurrent lower phase noise and

PLL figure of merit. The PFD1K operates with

a single positive or negative 3.3V supply, and

is packaged in a 40-pin, 6mm x 6mm ceramic

leadless surface mount package.

Features

• Product Highlights

• 40 GHz Maximum Frequency

• 1-127 Variable Modulus Prescalers

• DC-8GHz Phase Detector Operation

• Single +3.3V Supply

• Single-Ended or Differential inputs

and outputs

• Charge Pump digital control

• Charge Pump invert pin

• 6x6 Ceramic Leadless QFN

• Low Power Dissipation

Application

The PFD1K can be used as a general

purpose phase frequency detector with

integrated prescalers. It is ideally suited

to phase locked loop applications. The

prescalers can be programmed at a rate

greater than 100MHz, which makes

it an excellent choice for fractional-N

digital frequency synthesizers.

Pad Metallization

The QFN package pad metallization

consists of a 500-1000 micro-inch Sn63

automated solder dip process.
