The MM5837 shift register is 17 bits, taps at 14 and 17, with internal 
clock oscillator, the repeat length is from 1.1 to 2.4 secs.

Those taps make it maximal length, so the sequence is 2^17 - 1, or just 
about 128k bits long, so the internal osc is running from 50-120kHz.

Sure if you want to add some DSP!
