DESCRIPTION
The AK8186B is a multi-output clock generator with
sub-ps jitter performance. The on-chip VCO tunes
from 1.75GHz to 2.25GHz.
The distribution section has three pairs of LVPECL
buffers (6 outputs) and two pairs of LVDS buffers (4
outputs)/eight CMOS buffers (two per LVDS
outputs). The LVPECL outputs operate up to
1GHz, the LVDS outputs operate up to 800MHz
and the CMOS outputs operate up to 250MHz.
Each pair of the outputs has a divider. The
LVPECL outputs have the division range of 1 to 32.
The LVDS and CMOS outputs have the 1 to 1024.
The AK8186B operates at 3.3V and the LVPECL
outputs are supplied independently from 2.375V to
3.6V. The operating temperature range is from -40
to +85°C. The part is available in a 9mm 9 mm
64-pin Leadless-QFN (Pb free) package.
