Overview

The 5P1105 is a programmable fanout buffer intended for high-performance consumer, networking, industrial, computing, and data communications applications. Configurations may be stored in on-chip One-Time Programmable (OTP) memory or changed using the I²C interface.

The outputs are generated from a single reference clock. The reference clock can come from one of the two redundant clock inputs. A glitchless manual switchover function allows one of the redundant clocks to be selected during normal operation. Two select pins allow up to four different configurations to be programmed and accessible using processor GPIOs or bootstrapping. The device is available in a 24-pin VFQFPN 4mm x 4mm package, with an industrial operating temperature range of -40 °C to +85 °C.

Up to four high-performance universal differential output pairs:
- Low RMS additive phase jitter: 0.2ps
Four banks of internal non-volatile in-system programmable or factory programmable OTP memory
I²C serial programming interface
One additional LVCMOS output clock
Four universal output pairs:
- Each configurable as one differential output pair or two LVCMOS outputs
I/O standards:
- Single-ended I/Os: 1.8V to 3.3V LVCMOS
- Differential I/Os: LVPECL, LVDS, and HCSL
Input frequency ranges:
- LVCMOS reference clock input (XIN/REF) – 1MHz to 200MHz
- LVDS, LVPECL, HCSL differential clock input (CLKIN, CLKINB) – 1MHz to 350MHz

Hi, I'm Stephen Gutierrez, and over the course of the next few minutes, I will be sharing with you some of the features of Timing Commander, the new support tool for I.D.T. timing products.

Timing commander can support a single device or a family of devices from a single file. Currently, we are viewing a family of devices from the U.F.T. product line, and for this demo, we will be using the IDT-8T49N-283 device.

Timing Commander provides complete documentation that allows users to understand the function of each setting without having to consult the data sheet. As the user hovers over an element via a specific setting or a functional block, a tool tip containing detailed information appears. Many of the I.D.T timing products are complex, highly configurable devices. Timing Commander simplifies this configuration process by making the commonly used settings available at the top level.

In this case, all the user has to enter are the input frequencies and the output frequencies. As you have just noticed, the built-in optimization algorithm has configured the device on the fly, updating the functional blocks and the diagram with each of my inputs. Aside from providing information about valid settings, Timing Commander also validates the user inputs to ensure that they remain within the data sheet's specifications.

Here I have entered an invalid setting, and Timing Commander displays an error message plus a link that will direct me to the location of that error. Once corrected, the error message goes away. For users that want to access more detailed settings, Timing Commander provides a search tool that will help them quickly locate the settings.

For example, when searching for gain, Timing Commander will highlight the functional blocks and the setting that match the search term. In addition to the diagram view, Timing Commander also provides a bit-set view and a register view. The bit-set view displays the device settings with descriptive names and detailed information. The user can click on a bit-set to view more details or also search for a term. In addition to the bit-set view, the register view will allow a user to change individual settings.

The nice feature is that changes made in the bit-set view or register view will reflect back on the block diagram. In certain product families, Timing Commander offers additional tools and features, such as schematic symbols, termination guidelines, power calculations, and configuration specific phase noise simulations.

Timing Commander is an all-in-one resource for device information containing information from data sheets, modeling software, and simulation tools. Timing Commander and all supporting materials are available on IDT.com/go/TimingCommander.
