Skyworks Solutions Inc. SKY535x Differential Clock Buffers

The SKY535x0 differential clock buffers feature a selectable input clock using a 3:1 input mux, a single-ended reference output, and either 10, 8, or 4 differential outputs in two banks. Each of which can be selected as LVPECL, LVDS, HCSL, or tristate. The SKY535x1 differential clock buffers offer a selectable input clock using a 3:1 input mux, a single-ended reference output, and up to 20, 16, or 8 in-phase LVCMOS outputs in two banks.

The SKY53512/82/42 and SKY53513/83/43 differential clock buffers feature an I²C interface for selecting the input source to each of the two output banks. The I²C interface can also be used to select the output format for each of the two output banks, as well as the output state for each clock output. The devices support 10, 8, or 4 outputs in two banks, each of which can be set to LVPECL, LVDS, HCSL, 800mV LVDS, or complementary LVCMOS.

Each output bank has its dedicated 1.8V, 2.5V, or 3.3V output voltage supply. The series of fanout buffers can be paired with the Skyworks NetSync™ family of network synchronizer clocks, jitter attenuators, and clock generators and oscillators to deliver ultra-low-jitter clock tree solutions.

Evaluation Board Kits

The SKY53511‑A‑EVB, SKY53512‑A‑EVB, and SKY53513‑A‑EVB evaluation board kits allow users to quickly evaluate the performance of SKY53511/81/41, SKY53512/82/42, and SKY53513/83/43 ultra‑low additive jitter fanout buffers, respectively. The jumpers can be easily configured with no external software required, and SMA connections make it easy to connect to test equipment.
