QUAD ， 1比1 ，差分至2.5V ， 3.3V ， 5V LVPECL接收器 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 differential LVPECL/ECL receiver and a member of the HiperclocksTM family of High Performance Clock Solutions from IDT. The ICS853017 operates with a positive 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 VBB, can be used as a switching bias voltage on the unused input of the differential pair. VBB can also be used to rebias AC coupled inputs.
FEATURES
