Features

Programmable Clock Divide by 1/2/4/8/16/32
Delay Adjustment in Multiples of 1/2 Clock Cycles or in 60 Steps of 20 ps (Typ.)
–170 dBc/Hz Noise Floor @ 100 MHz Output

Up to 4 GHz Operation with 800 mV_P-P LVPECL Output
3.3V Operation (or 5V Operation with Optional On-Chip Regulator for Best Performance)

Additional Details

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.

APPLICATIONS

Basestation Digital Pre-Distortion Paths (DPD)
High Performance Automated Test Equipment (ATE)
Backplane Clock Skew Management
Phase Coherence of Multiple Clock Paths
Clock Delay Management ton Improve Setup & Hold Time Margins
PCB Signal Flight Time Offset Circuits
Track and Hold Circuits for ADC/DACs
