AD9516-2 is a 14-channel clock generator with an integrated 2.2 GHz VCO.
The AD9516-2 is a 14‑output clock generator with an integrated 2.2 GHz VCO. It offers low phase‑noise PLL operation, programmable delays, and automatic reference switchover. The device supports LVPECL, LVDS, and CMOS output standards and can be powered from a single 3.3 V supply.
The handbook provides detailed specifications, functional block diagrams, timing characteristics, and application guidance for high‑speed data‑converter clocking, networking line cards, and wireless transceivers. It also includes power‑supply requirements, pin descriptions, and recommended PCB layout practices for CMOS outputs.
| LVPECL output frequency | 1.6 GHz (6 pairs) |
|---|---|
| LVDS output frequency | 800 MHz (4 pairs) |
| CMOS output frequency | 250 MHz |
| Supply voltage (Vs) | 3.3 V (typical) |
| Operating temperature range | -40 °C to +85 °C |
The device provides six LVPECL output pairs that can operate up to 1.6 GHz.
It operates from a 3.3 V supply (typical 3.3 V, range 3.135 V to 3.465 V).
The phase noise is –107 dBc/Hz at 100 kHz offset when the VCO is at 2175 MHz.
Four CMOS output pairs are available, each operating up to 250 MHz and compatible with 3.3 V CMOS logic.
