Description
General part information
HMC988 Series
The HMC988LP3E is a an ultra low noise clock divider capable of dividing by 1/2/4/8/16/32. It is a versatile device with additional functionality including adjustable output phase, adjustable delay in 60 steps of ~ 20 ps, a clock synchronization function, and a clock invert option.Housed in a compact 3 × 3 mm SMT QFN package, the clock divider offers a high level of functionality. The device works with 3.3V supply or may be connected to 5V supply and utilize the optional on-chip regulator. This on-chip regulator may be bypassed.Up to 8 addressable HMC988LP3E devices can be used together on the SPI bus.The HMC988LP3E is ideally suited for data converter applications with extremely low phase noise requirements.APPLICATIONSBasestation Digital Pre-Distortion Paths (DPD)High Performance Automated Test Equipment (ATE)Backplane Clock Skew ManagementPhase Coherence of Multiple Clock PathsClock Delay Management ton Improve Setup & Hold Time MarginsPCB Signal Flight Time Offset CircuitsTrack and Hold Circuits for ADC/DACs
