The CDCLVP111 clock driver distributes one differential clock pair of LVPECL input,
(CLK0, CLK1) to ten pairs of differential LVPECL clock (Q0, Q9) outputs with minimum skew for clock
distribution. The CDCLVP111 can accept two clock sources into an input multiplexer. The CDCLVP111
is specifically designed for driving 50-Ω transmission lines. When an output pin is not used,
leaving it open is recommended to reduce power consumption. If only one of the output pins from a
differential pair is used, the other output pin must be identically terminated to 50 Ω.
The VBB reference voltage output is used if single-ended input
operation is required. In this case, the VBB pin should be connected to
CLK0 and bypassed to GND through a 10-nF capacitor.
However, for high-speed performance up to 3.5 GHz, the differential mode is strongly
recommended.
The CDCLVP111 device is characterized for operation from –40°C to 85°C.
