The CDCLVP1102 is a highly versatile, low additive jitter buffer that can generate two copies of LVPECL clock outputs from one LVPECL, LVDS, or LVCMOS input for a variety of communication applications. It has a maximum clock frequency up to 2 GHz. The overall additive jitter performance is less than 0.1 ps, RMS from 10 kHz to 20 MHz, and overall output skew is as low as 10 ps, making the device a perfect choice for use in demanding applications.
The CDCLVP1102 clock buffer distributes a single clock input (IN) to two pairs of differential LVPECL clock outputs (OUT0, OUT1) with minimum skew for clock distribution. The inputs can be LVPECL, LVDS, or LVCMOS/LVTTL.
The CDCLVP1102 is specifically designed for driving 50-Ω transmission lines. When driving the inputs in single-ended mode, the LVPECL bias voltage (VAC_REF) should be applied to the unused negative input pin. However, for high-speed performance up to 2 GHz, differential mode is strongly recommended.
The CDCLVP1102 is characterized for operation from 40°C to 85°C and is available in a QFN-16, 3-mm × 3-mm package.
