PRELIMINARY
QUAD, 1-TO-1, DIFFERENTIAL-TO-2.5V,
3.3V, 5V LVPECL RECEIVER
GENERAL DESCRIPTION
The ICS853017 is a quad 1-to-1, 2.5V/3.3V/5V dif-
ICS
ferential LVPECL/ECL receiver and a member of the
HiPerClockS™ _HiperclocksTM _{family of High Performance Clock So-}
lutions from IDT. The ICS853017 operates with a posi-
tive or negative power supply at 2.5V, 3.3V or 5V,
and can accept both single-ended and differential inputs. For single-
ended operation, an internally generated voltage, which is avail-
able on output pin V_BB, can be used as a switching bias voltage on
the unused input of the differential pair. V_BB can also be used to
rebias AC coupled inputs.
