The CDCLVP111-SP 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-SP can accept two clock sources into an input multiplexer. The
CDCLVP111-SP 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 via a 10-nF capacitor.
For high-speed performance, the differential mode is strongly recommended.
The CDCLVP111-SP is characterized for operation from –55°C to 125°C.
