Valpey Fisher debuts jitter attenuator for synchronous Ethernet applications

Jan. 18, 2008
JANUARY 18, 2008 -- Valpey Fisher says its Jitter Attenuator features two LVCMOS outputs with a frequency of 25 MHz that can be locked to an input reference frequency. Two select inputs, S1 and S0, allow the user to select one of three preset input frequencies or a free-run mode.

JANUARY 18, 2008 -- Valpey Fisher Corp. (search for Valpey Fisher) recently introduced the VFJA905 Jitter Attenuator, an integrated clock/PLL timing solution for 1G and10G synchronous Ethernet applications.

The Jitter Attenuator features two LVCMOS outputs with a frequency of 25 MHz that can be locked to an input reference frequency. Two select inputs, S1 and S0, allow the user to select one of three preset input frequencies or a free-run mode.

The VFJA905 provides a selectable input frequency range from 8 KHz to 200 MHz and an output frequency range of 10 MHz to 200 MHz. It features ultra_low output jitter (0.18 ps RMS 12 KHz to 20 MHz). The device operates from a +3.3V DC power supply and typically consumes 150 mW of power.

The VFJA905 is available in a 19.5 mm x 15.5 mm surface mount package and is RoHS 6/6 compliant.
