MaxLinear, Inc. Clock/Timing - Application Specific XRT8001IDTR-F

The XRT8001IDTR-F is a dual-phase-locked loop chip designed for generating low jitter output clock signals suitable for synchronization in wide area networking systems. It can produce two integer multiples of 8kHz, 56kHz, and 64kHz while locking onto incoming reference frequencies of 1.54MHz (T1), 2.048MHz (E1), 8kHz, 56kHz, or 64kHz. The device features pre-programmed multipliers and dividers that can be selected via a serial port, allowing for flexible configuration. This clock generator operates in six different modes, including Forward/Master, Reverse/Master, and Slave modes, among others. It supports output clock frequencies ranging from 8kHz to 16.384MHz and provides sync output options of 8kHz or 64kHz. The XRT8001IDTR-F is designed for low power consumption (40 - 100mW) and operates within a temperature range of -40¬8C to +85¬8C. It is available in an 18-lead SOIC package and is pin compatible with the XRT8000 series, making it a versatile choice for various applications, including T1/E1 access equipment, ISDN routers, and system synchronizers.
