DEMO CIRCUIT 1418 QUICK START GUIDE LTC6604-X

DESCRIPTION

Demonstration circuit 1418 features the LT6604-XX se-

ries of a dual, matched, fully differential 4

order low-

pass filter

approximating a Chebyshev frequency re-

sponse

. The cutoff frequencies (Fc) of LT6604-XX are:

2.5MHz, 5MHz, 10MHz and 15MHz. (see Table 1).

The

LT6604-XX combines a lowpass filter with two fully

differential matched amplifiers for driving the differ-

ential inputs of a dual analog to Digital Converter

(ADC) and band-limiting the baseband signal of digi-

tal communications receiver.

Each LT6604-XX filter IC

requires only two external input resistors to set the fil-

ter’s differential gain.

A DC1418 board contains an

LT6604-XX configured with input resistors as two unity

gain differential amplifiers/lowpass filters.

Gains greater than one require changing the input resis-

and the DC1418 schematic).

Connection to the differential input and output of a

DC1418 is through SMA connectors. On-board jumpers

configure the DC1418 for dual or single supply opera-

tion and internal or external output common (VOCM)

mode biasing. The differential input of a DC1418 is AC

coupled and can be configured for DC coupling by re-

placing shorting the input capacitors with zero ohms

surface-mount resistor jumpers. In addition, the

DC1418 has surface-mount pads to add input passive

components for input signal filtering and DC biasing.

QUICK TEST SET UP

Quick Test Procedure

A DC1418 has two pairs of differential inputs,

Vin+A/Vin-A and Vin+B/Vin-B and two pairs of differen-

tial outputs Vout-A /Vout+A and Vout-B/Vout-B.

1. Testing the VinA to VoutA Signal Path.

Connect a DC1418 board as shown in Figure 2 (connect

signal generator to Vin+A and terminate Vin-A with a 50

ohm terminator). Set the generator for a 1MHz, 2Vp-p,

and sinewave. The oscilloscope channels connected to

Vout-A and Vout+A show a 1MHz, 1Vp-p, sinewave (see

Note 1).

Dual Power Supply

Oscilloscope (≥100MHz)

2. Testing the VinB to VoutB Signal Path.

Connect signal generator to Vin+B and terminate Vin-B

with a 50 ohm terminator. Set the generator for a 1MHz,

2Vp-p, and sinewave. Connect oscilloscope channel 1 to

Vout-B and channel 2 to Vout+B. The oscilloscope

channels connected to Vout-B and Vout+B show a

1MHz, 1Vp-p, sinewave.

Note 1:

For unity gain testing the DC1418 inputs must

be ideally driven by a zero ohm source (the outputs of a

high speed differential amplifier). However with the 50

ohm impedance of the generator’s output and termina-

tor is in series with the input resistors and the input to

output gain is less than one.

Note 2:

For single supply testing set the JP2 shunt to

SINGLE.
