5.32. Revision Identification
With the Si3056 the system designer can determine the revision of the Si3056 and/or the line-side device. The
REVA[3:0] bits (Register 11, bits 3:0) identify the revision of the Si3056. The REVB[3:0] bits (Register 13, bits 3:0)
identify the revision of the line-side device. Table 22 lists revision values for all devices and might contain future
revisions not yet in existence.
