(replaced by two resistors) Added: R103 200 ohms 1% 0603 R104 510 ohms 1% 0603 Moved: C175 bypass for U44 C181 bypass for U44 Changed: U44 package type and location was MAX538 8 pin SOIC now MAX5302 uMax8L R36G1,2,3,4,5,6 Value changed was 620K in 0603 now 390k in 0603 Also various routing changes and moved vias to aleviate some soldering problems. Changes from Revision 6 to Revision 7 are summarized here: Clock Delays were moved from top side to bottom side. LHC voltage regulator position moved slightly. Capacitors and resistors near the regulator were also moved.
