GENERAL DESCRIPTION
The S4406 BiCMOS clock generator provides 12 TTL
outputs with less than 500 ps of skew. Implemented
in AMCC’s 1.0
μ
BiCMOS technology, the internal
PLL and divider/delay selector logic allow the user to
individually tailor the (4) TTL output groups to the
system’s needs. The internal VCO can operate be-
tween 160 to 266 MHz, and the programmability al-
lows the user to generate output clocks in the 20–66
MHz range.
The S4406 offers the user the ability to select the
appropriate phase and frequency relationship for
each of the four groups of three TTL clock outputs.
In addition to clock doubling and inversion functions,
the S4406 allows any output groups to lead or lag the
others by the minimum phase delay of 3.75–6.25 ns.
