The maximum number of cascading AS1112 devices depends on the application system and is in the range of 40 devices. The minimum fre-
quency needed can be calculated by the following equations:
f GSCLK = 4096 x f UPDATE
Where:
f GSCLK is the minimum frequency needed for GSCLK;
f UPDATE is the update rate of whole cascaded system.
f CLK = 193 x f UPDATE x n
Where:
f CLK is the minimum frequency needed for CLK and SIN;
f UPDATE is the update rate of whole cascaded system;
n is the number of cascaded of AS1112 devices.
