AV9107C-19CS08

Integrated Circuit Systems, Inc. AV9107C-19 AV9107C-20 Frequency Generator for Fibre Channel Systems 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. Features • • • • • • • • Generates one or two 106.25 MHz clocks from a 17 MHz crystal Less than 60ps one sigma jitter Less than ±200ps absolute jitter Output skew less than ±100ps on two channel version (-20) Rise/fall times less than 4ns driving 15pF On-chip loop filter components 3.0V-5.5V supply range 8-pin, 150-mil SOIC package Applications • Specifically designed to support the high-speed clocking requirements of fibre channel systems Block Diagram AV 9107-19 20 RevC091897P ICS reserves the right to make changes in the device data identified in this publication without further notice.
