Product details

2.65 GHz PLL clock generator with six LVPECL outputs

The AD9518-1ABCPZ-RL7 integrates a PLL and VCO to generate a clean clock up to 2.65 GHz, then fans it out to six LVPECL outputs. That means one chip replaces a separate synthesizer and a distribution buffer — a single BOM line for the high-speed clock tree in a base station or test instrument. Input accepts CMOS, LVDS, or LVPECL references, so it can lock to a TCXO, a crystal oscillator, or a backplane clock without level translation.

Supply rail and temperature range for outdoor gear

The 48-LFCSP-VQ (7x7) exposed-pad package helps pull heat into the PCB ground plane; a 2-layer board with a solid thermal via array under the pad keeps the junction below the 85°C ambient limit.

Frequently asked questions

What is the maximum output frequency of AD9518-1ABCPZ-RL7?

The maximum output frequency is 2.65 GHz, specified at the LVPECL outputs. That covers the reference clock for most high-speed ADCs, DACs, and FPGA transceivers up to 10 Gbps line rates.

Does AD9518-1ABCPZ-RL7 require an external PLL loop filter?

Yes — the PLL requires an external loop filter (typically a series resistor and capacitor network) connected to the charge-pump output. The datasheet provides design equations for the loop bandwidth and phase margin based on the reference frequency and VCO gain.

How many clock outputs does AD9518-1ABCPZ-RL7 provide?

It provides six LVPECL outputs from a single input (1:6 ratio). Each output can be independently divided down from the VCO frequency, so you can generate multiple clock rates from one PLL.

What is the closest functional alternative to AD9518-1ABCPZ-RL7?

The AD9518-3ABCPZ-RL7 is the closest sibling — same package, same 1:6 LVPECL output count, same supply and temperature range, but with a maximum frequency of 2.25 GHz instead of 2.65 GHz. If your system clock target is below 2.25 GHz, the -3 variant is a drop-in alternative.
