IDT23S08E-5HDCGI

The IDT23S08E-5HDCGI is a programmable, fractional-N PLL and clock generator integrated circuit (IC) with a wide operating range. It combines a mixer, digital divider, VCO, and control logic in one clock IC and is suitable for clock and data distribution applications, as well as clock and timing synchronization and conversion purposes. In addition, the device includes a non-volatile memory (EEPROM) and two programmable, selectable sources of reference input signals. The IDT23S08E-5HDCGI is designed for operations over a wide ambient temperature range and is specified for operation over the 0-70° C temperature range.

The IDT23S08E-5HDCGI is a PLL with a voltage-controlled oscillator (VCO) that generates an output frequency based on the reference input frequency. This frequency is adjustable within the range of 4.0 to 600.0 MHz. The non-volatile, standard serial EEPROM memory unit provides a means of storing two complete PLL configuration settings. A programmable input reference enables the device to operate with two independent sources of reference clocks.

The device outputs four differential clock signals, including a clock corresponding to the reference frequency and three clock outputs derived from the reference frequency. The reference clock can be adjusted from 4.0 MHz to 600.0 MHz and the derived clocks can be adjusted from 12KHz to 600MHz. The three derived clocks are synchronized to the reference clock, and the output port has the capability to provide clock synchronization between the outputs of the device.

The device’s digital logic core and EEPROM memory are provided by an externally accessible control interface that facilitates access to the clock configuration parameters. The EEPROM memory can be programmed using the IDT23S08E-5HDCGI’s integrated JTAG (Joint Test Action Group) speed-reconfigurable interface. The programmable parameters enable users to tailor the device to their specific application, while the configurable port provides additional functionality by allowing communication between two disparate systems.

The control logic within the device enables on-board frequency synchronization and can be used to generate multiple sources of the same frequency output. On-board diagnostics are also available, allowing users to monitor the status of the device, including the internal temperature and voltage of the voltage-controlled oscillator (VCO). The device is designed to operate in either autonomous or synchronized modes. In autonomous mode, the device adjusts the output frequency based on the reference frequency, while in synchronized mode, the device can lock to a reference input source.

The benefits of the IDT23S08E-5HDCGI include flexible control logic and pre-programmed operational settings. The device is also capable of providing multiple synchronized sources from a single reference input, making the device ideal for multi-channel or redundant applications. Additionally, the device provides power efficiency due to its low power consumption levels and has been tested and verified to exceed performance requirements.

The IDT23S08E-5HDCGI is an advanced clock generator IC that can provide multiple frequencies with wide operating ranges. The integrated control logic and EEPROM memory makes the device easy to configure and can be used for both clock and data distribution, and clock and timing synchronization applications. The device is optimized for low power consumption and provides a reliable, cost-effective solution for multi-channel and redundant applications.
