... Document Number: 38-07288 Rev. *E 1:12 Clock Distribution Buffer Description The CY29948 is a low-voltage 200-MHz clock distribution buffer with the capability to select either a differential LVPECL or a LVCMOS/LVTTL compatible input clock. The two clock sources can be used to provide for a test clock as well as the primary system clock ...
