Description

The MSSCSA is a single chip 1/6th octave 6

band spectrum analyzer whose center frequencies

are controlled by a single master clock.

The

center frequencies are set at

1.12246, 1.2599,

1.4142, 1.5874, 1.78179 and 2 (normalized).

The sample to corner is 25:1 for the 2 Hz nor-

malized output and 44.545:1 at the 1.122 Hz

normalized output.

The MSSCSA’s 1.178179 Hz

output is 2 MHz (Clock at 25 MHz).

Multiple MSSCSA can be connected for spectrum

analysis by taking the master clock of the high

frequency filter and dividing by 2.

The MSSCSA includes two uncommitted op amps

for adding additional fixed gain for microphone or

other low level applications.

A digitally program-

mable gain stage provides 0, 10 or 20 dB of

gain.

The PD pin selects power down, low

power for ultrasonic applications and regular

power for operation at 2 MHz center frequency.

The MSSCSA is fabricated in 0.6 um CMOS

process for low power consumption and opera-

tion from 3.0 to 5.5 VDC
