Description

The 5P49V5944 is a programmable clock generator 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. This is Renesas' fifth generation of programmable clock technology (VersaClock^® 5). The frequencies are generated from a single input reference clock. The input reference can be either a crystal or an LVCMOS reference clock.

Two select pins allow up to four different configurations to be programmed and accessible using processor GPIOs or bootstrapping. The different selections may be used for different operating modes (full function, partial function, and partial power down), regional standards (US, Japan, Europe), or system production margin testing.

Applications

PCI Express 1.0/2.0/3.0
Broadcast video/audio timing
Multi-function printer
Processor and FPGA clocking
Any-frequency clock conversion

This video provides an overview of the VersaClock 5 programmable clock generator family, including the 5P49V5901, 5P49V5913, 5P49V5914, 5P49V5923, 5P49V5925, 5P49V5927, 5P49V5929.

The VersaClock 5 family is an in-system programmable clock generator featuring up to four universal output pairs capable of producing independent frequencies up to 350 MHz configurable as HCSL, LVPECL, LVDS, or dual LVCMOS outputs. The highly integrated device consolidates four differential or eight single-ended clock generators and can store up to four different configuration settings, helping to minimize board space and bill-of-materials. Upon request, devices may be factory-programmed to the customer’s desired configuration.

VersaClock® 5 is a low-power programmable clock generator with best-in-class jitter performance with less than 0.7psec RMS phase jitter from 12KHz to 20MHz. The highly integrated device consolidates four differential or eight single-ended clock generators and can store up to four different configuration settings, helping to minimize board space and bill-of-materials. The high-performance clock generator operates at less than 100mW core power (50 percent lower than competing devices), helping to ease system thermal constraints and reduce operating power expenses.

VersaClock 5 can take a crystal or a clock input. It has 4 fractional output dividers which allow the programming of 4 independent frequencies up to 350MHz. The four universal output pairs are independently configurable as HCSL, LVPECL, LVDS, or dual LVCMOS outputs. It also features a reference clock output. The fractional output dividers driving each output pair are easily programmed via I2C while the device is operating in the system, lending itself to system tuning and margin testing. Unlimited in-system reprogramming is possible via I2C, whereas four banks of one-time programmable non-volatile memory provide flexibility for multi-project inventory consolidation or design changes in field or production units. Upon request, devices may be factory-programmed to the customer's desired configuration.

This is a video introduction and demonstration of the VersaClock 5 Evaluation Board. This device uses Renesas's Timing Commander™ software platform, allowing engineers to configure and program their devices with an intuitive, time-saving graphical user interface (GUI).

The 5P49V5901 is an in-system programmable clock generator featuring four universal output pairs capable of producing independent frequencies up to 350 MHz in various output types. With RMS phase jitter less than 0.7 picoseconds over the full 12 kHz to 20 MHz integration range, the new device meets the stringent jitter requirements of PCI Express® Gen 1/2/3, USB 3.0, and 1G/10G Ethernet. The high-performance clock generator operates at less than 100 mW core power (50 percent lower than competing devices), helping to ease system thermal constraints, reduce operating power expenses, and maximize battery life.

The 5P49V5901's four universal output pairs are each independently configurable as HCSL, LVPECL, LVDS, or dual LVCMOS outputs. The fractional output dividers driving each output pair are easily programmed via I2C while the device is operating in the system, lending itself to system tuning and margin testing. Unlimited in-system reprogramming is possible via I2C, whereas four banks of one-time programmable non-volatile memory provide flexibility for multi-project inventory consolidation or design changes in field or production units. Upon request, devices may be factory-programmed to the customer's desired configuration.
