2.3 Clocks
A MCH may support clock distribution for up to 3 clocks per module. Each AMC slot
supports two clock inputs (MCH to AMC), CLK1/3, and one clock output (AMC to
MCH), CLK2. All clocks use LVDS compliant drivers/receivers. UTCA-5503 supports
two different clock architectures, redundant and non-redundant as shown below. The
redundant implementations are for dual MCH systems, and the non-redundant are
for single MCH systems. This requires the implementations of different backplanes
for non-redundant and redundant architectures.
