Texas Instruments CDCLVP1216RGZT

Description
The CDCLVP1216 is a versatile, low additive jitter buffer that generates 16 copies of LVPECL clock outputs from one of two selectable LVPECL, LVDS, or LVCMOS inputs for various communication applications. It has a maximum clock frequency of 2 GHz. The CDCLVP1216 features an onchip multiplexer (MUX) for selecting one of two inputs configurable through a control pin. 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 30 ps, making it suitable for demanding applications.
The CDCLVP1216 clock buffer distributes one of two selectable clock inputs (INO, IN1) to 16 pairs of differential LVPECL clock outputs (OUTO, OUT15) with minimum skew for clock distribution. It can accept two clock sources into an input multiplexer, which can be LVPECL, LVDS, or LVCMOS/LVTTL.
The CDCLVP1216 is designed for driving 500 transmission lines. When driving the inputs in singleended mode, the LVPECL bias voltage (VAC REF) should be applied to the unused negative input pin. However, for highspeed performance up to 2 GHz, differential mode is strongly recommended.
The CDCLVP1216 is packaged in a small 48pin, 7mm x 7mm QFN package and is characterized for operation from 40°C to 85°C.
