General Description

The AV9107C-19 and AV9107C-20 are high-speed clock generators designed to support fibre channel system requirements. The AV9107C-19 generates a single copy of the 106.25 MHz from a 17 MHz crystal. The AV9107C-20 provides a second copy of the 106.25 MHz clock with output skew less than ±100ps. An exact frequency multiplying ratio ensures better than –100 ppm frequency accuracy using a standard AT crystal with external load capacitors (typically 33pF±5 for an 18pF load crystal). Achieving ±100 ppm over four years requires the crystal to have a ±20 ppm initial accuracy, ±30 ppm tempera-ture and ±5 ppm/year aging coefficients.
