AK8186B - Multi Output Clock Generator

General 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).

Key Features

  • Low phase noise PLL : RMS Jitter < 300fs On-chip VCO tunes from 1.75GHz to 2.25GHz External VCO/VCXO to 500MHz optional 1 differential or 2 single-ended Inputs Reference Switchover/Holdover modes Lock Detect 3 pairs of 1GHz LVPECL outputs 2 pairs of 800MHz LVDS outputs 8 250MHz CMOS outputs (two per LVDS) Serial control register interface 3.3V+/-5% Operating Voltage 2.5V-3.3V LVPECL Drive Voltage Operating Temperature: -40 to +85°C Package: 64-pin Leadless QFN (Pb free) Pin compatible with AD951.
