CDCLVP111-SP 1:10 High Speed Clock Buffer with Selectable Input Clock Driver |

CDCLVP111-SP (ACTIVE) 1:10 High Speed Clock Buffer with Selectable Input Clock Driver



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.
