The new UFT devices are single-chip solutions capable of generating eight different output frequencies with less than 300 femtoseconds RMS phase jitter over the standard 12 kHz to 20 MHz integration range, said the mixed-signal semiconductor solution provider.
The IDT 8T49N28x UFT family of timing devices offers eight independently-programmable clocking outputs with the flexibility to apply any input frequency and select any output frequency, according to the company. The devices' high level of integration and low jitter eliminates the need for separate frequency translation, redundancy management, and jitter attenuation devices, empowering system designers to save cost and board area by consolidating those functions into a single device.
The IDT 8T49N28x devices are available with one or two PLLs in a single package, depending on the needs of the application. When configured as a frequency synthesizer, the device can utilize a low-cost, readily-available 10MHz to 40MHz crystal to produce any frequency from 8kHz to 1.0GHz, regardless of the crystal frequency used, the company said. In a frequency translator configuration, the devices accept up to four input reference clocks per PLL from 8kHz to 875MHz, switching between them as necessary to generate any output frequency from 8kHz to 1.0GHz. Each output is individually programmable as LVPECL, LVDS, or as a pair of LVCMOS signals.
IDT offers products from full-featured system solutions to simple clock building-block devices. IDT has also expanded its portfolio to include frequency control products, such as the XpressO oscillators from
