3 Description

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.
