Operating from a 2.7V to 5.5V supply, the UMA1021M has an RF frequency synthesis range from 300 MHz to 2.2 GHz. In combination with its low comparison frequency breakthrough, this permits straightforward PLL designs that use simple passive loop filters. The UMA1021M operates at crystal reference frequencies up to 35 MHz, and has independently programmable reference and main frequency dividers. When turned on, both the dividers and phase detector are immediately synchronized to avoid large random phase errors. Programming is via a standard 3-wire serial interface and is compatible with other frequency synthesizers in Philips Semiconductors' UMA10xx family.
Actual prices depend on the importing country.
Production volumes are available now on a lead time of around eight weeks after receipt of order. To jump-start design cycles, technical support is already available from Philips Semiconductors in the form of a sampling kit and application note. In this capacity, he has driven the regional sales activities to record levels and has increased Quickturn's presence in new markets. In his new assignment, Jordan will manage all field sales and support operations in Quickturn's 16 sales offices located throughout North America. Comments on our editorial are welcome.
