SL28540ALC Description

Short technical summary and product information.

The Skyworks Solutions SL28540ALC is an integrated circuit designed as a low-power clock generator specifically for Intel mobile platforms. It complies with the Intel CK540 UMPC clock specification and features a selectable frequency for differential CPU clocks, alongside dedicated clocks for SRC (100 MHz), DOT (96 MHz), USB (48 MHz), and PCI (33 MHz).

 

This device incorporates low-power push-pull type differential output buffers, an integrated voltage regulator, and series termination resistors on differential clocks. The VDD_IO is scalable from 3.3V down to 1.05V, and it offers an 8-step drive strength control for single-ended clocks. The SL28540ALC supports I2C communication with readback capabilities and includes an ideal Lexmark Spread Spectrum profile for reduced electromagnetic interference (EMI).

 

Packaged in a 56-pin QFN (8x8) with an exposed pad, the SL28540ALC is designed for surface mounting. It operates within a temperature range of 0°C to 85°C and requires a voltage supply between 3.135V and 3.465V. The input is a crystal, and it features a ratio of 1:17.
