Low-Jitter Clock Chip Puts Out 35.328 MHz

The MAX9476 generates six identical, buffered, low-voltage TTL outputs at 35.328 MHz, all synchronized with an 8-kHz input clock. Designed by Maxim Integrated Products, this clock chip targets ADSL/VDSL central-office linecards and telecom network systems. It can track the input reference within ±100 ppm. An additional low-jitter, 8-kHz clock output can be used as a reference clock for other parts of the system. This output also can automatically detect the absence of the 8-kHz reference and lock to 35.328 MHz with an accuracy of ±25 ppm. It operates from a single supply from ­40°C to 85°C. Prices start at $6.14 in lots of 1000 units and up.
