The MPC9111 is a low skew 1–to–9 differential HSTL compatible
output fanout buffer. The device is functionally equivalent to the
MC100LVE111 device. The device accepts either LVPECL or HSTL
compatible input levels and provides 9 low skew differential HSTL
compatible outputs. The device operates from a single 3.3V VCC supply.

The MPC911 HSTL outputs are not realized in the conventional
manner. To minimize part–to–part and output–to–output skew the HSTL
compatible output levels are generated with an open emitter architecture.
The outputs are pulled down with 50Ω to ground rather than the typical
50Ω to V
DDQ
pullup of a “standard” HSTL output. Because the HSTL
outputs are pulled to ground the MPC911 does not utilize the V
DDQ
supply
of the HSTL standard. The output levels are derived from VCC, an internal
regulator minimizes the output level variation with VCC variations.
