Integrated Device Technology has introduced a family of clock buffers that are claimed to deliver best-in-class jitter performance in a compact package. The 5PB11xx family provides low-jitter metrics of less than 50fs RMS additive phase jitter (12KHz to 20MHz), offering system designers greater jitter margin than competitive products to help them meet system clock requirements.

The buffers are suited for high-end consumer, industrial, data communications, telecommunications and computing applications where both timing budget and board space are at a premium.

The 5PB11xx buffers are available with 2-10 LVCMOS outputs and can support 1.8, 2.5 and 3.3V power supplies and outputs. They have a low output skew of 50ps with only 14mA core current consumption. All the devices in the buffer family are characterised at an extended temperature of -40 to +105°C enabling the buffers to meet the requirements of automotive infotainment applications as well.

Dave Shepard, Vice President and General Manager, Timing and RF Division, IDT, comments: “As designs become more complex with tighter timing requirements, jitter will only grow as an obstacle for system designers. Our 5PB11xx fanout buffers give these engineers more elbow room so they can continue to innovate while meeting stringent jitter demands.”

The small die size enables the chip to fit within an 8-pin DFN package as small as 2x2mm. The 5PB11xx buffers start at $0.80 for 1,000 unit pricing and are available within a short lead time.
