loads. A sync current following SYNC input
timing is added to the I

output. BLANK will override
RGB inputs, setting I

currents to zero when
BLANK = L. Although appropriate for many applications
the internal 1.25V reference voltage can be overridden by the
V
REF
input.
Few external components are required, just the current
reference resistor, current output load resistors, bypass
capacitors and decoupling capacitors.
Package is a 48-lead LQFP. Fabrication technology is
CMOS. Performance is guaranteed from 0 to 70擄C.
