3 Description

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 50Ω transmission lines. When an output pin is not used, leaving the pin 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 50Ω.

The VBB reference voltage output is used if single-ended input operation is required. In this case, the VBB pin must be connected to CLK0 and bypassed to GND using a 10nF capacitor.

For high-speed performance, the differential mode is strongly recommended.

The CDCLVP111-SP is characterized for operation from –55°C to 125°C.
