SM5807

The SM5807 digital filter is manufactured using MOLYGATE CMOS technology developed by NPC and is implemented in 4 times oversampling scheme with the stopband  (above 24.1 kHz) attenuation of more than 50 dB and the passband ripple of less than +0.05 dB. Two channel filters are provided and the 4 times oversampled output signal of each channel can be independently obtained. Because of this 4 times oversampling, the requirement of the analog filter can be greatly relaxed, and also the serious data format reduces the size of hardware required in the system design.

Features of the SM5807 are:(1)filter structure:4 times oversampling, 2 channel filters, 2 stages linear phase FIR filter, overflow limiter, internal crystal oscillator circuit, clock buffer;(2)input/output:16-bit serial data input and output (2's complement, MSB first) and TTL compatible;(3)power supply 5 +/- 0.5 V;(4)16-pin plastic DIP/SOP;(5)molygate CMOS technology.

The absolute maximum ratings of the SM5807 can be summarized as:(1)supply voltage:-0.3 to +7.0 V;(2)input voltage:-0.3 to VDD+0.3 V;(3)storage temperature:-40 to +125;(4)power dissipation:250 mW;(5)soldering temperature:255;(6)soldering time:10 sec..
