The HMC988LP3E programmable clock divider and delay has various typical applications, including: 1. Delaying the output signal by one cycle of the input signal using the slip function, which causes a phase shift in the output signal . 2. Selecting the launch phase of the output signal relative to the input signal by programming reg06h. 3. Offering modular configuration with up to 8 devices on one SPI bus, each controlled individually with 3-bit addressable chip addresses . 4. Providing synchronization function, adjustable fine delay, trigger options, and optional on-chip regulator . 5. Allowing the output delay to be adjusted in ~20 ps steps using reg07h. 6. Implementing sync and slip functions using the external "triG" pin or by other means . 7. Supporting flexible input stage that can be driven single-ended or differential with various signals, with an input impedance of 50 Ω single-ended or 100 Ω differential . Hence, the HMC988LP3E programmable clock divider and delay finds applications in signal phase shifting, synchronization, modular configurations, and fine delay adjustments.

The HMC988LP3E clock divider offers adjustable output phase with soft/hard reset sync and adjustable delay in 60 steps of ~20 ps. It has a flexible input interface that is compatible with LVPECL, LVDS, CML, and CMOS signals. The device can be driven single-ended or differential, with an input impedance of 50 Ω single-ended or 100 Ω differential. The output driver provides 800 mVpp LVPECL into 50 Ω single-ended. It also supports up to 8 addressable dividers per SPI bus and can operate at 3.3 V or 5 V with an optional on-chip regulator for best performance. The clock divider is housed in a compact 3x3 mm leadless SMT package.
