Detailed Description

The MSLSA is a single chip 1/6th octave-wide 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 100:1 for the 2 Hz normalized output and 178.16:1 at the 1.122 Hz normalized output. The MSLSA's 1.1.12246 Hz output is @ 55.1 kHZ ( Clock at 5 MHz). Multiple MSLSA can be connected for spectrum analysis by taking the master clock of the high frequency filter and dividing by 2.

The MSLSA includes two uncommitted op amps for adding additional fixed gain for microphone or other low level applications. A digitally programmable 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 at 2 MHz frequency operation. The MSLSA is fabricated in 0.6 um CMOS process for low power consumption and operation from 3.0 to 5.5 VDC.
