Texas Instruments CDCM1804RTHT

Description
The CDCM1804 is a clock driver that distributes one pair of differential clock inputs to three pairs of LVPECL differential clock outputs (Y[2:0] and Y[2:0]) and one LVCMOS singleended output (Y3). It is designed for clock distribution applications and features low output skew (15 ps typical for LVPECL outputs) and a programmable output divider for two LVPECL outputs and the LVCMOS output. The CDCM1804 also provides a VBB bias voltage output for singleended input signals.
