ICS9248-80 - General Purpose 133MHz System Clock

Description

The ICS9248-80 is a general purpose system clock.

Features

  • through CLK_STOP#. Spread spectrum may be enabled through I2C programming. Spread spectrum typically reduces EMI by 8dB to 10 dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9248-80 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations. Features • Extended temperature range (-20°C to +70°C) • Output features: - 8 CLK outputs @ 3.3V, up to 133.34MHz. - 1-R.

ICS9248 - 80 General Purpose 133MHz System Clock General Description The ICS9248-80 is a general purpose system clock. It provides 8 output CLKs, 1 REF CLK and excellent power management features through CLK_STOP#. Spread spectrum may be enabled through I2C programming. Spread spectrum typically reduces EMI by 8dB to 10 dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9248-80 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations. Features • Extended temperature range (-20°C to +70°C) • Output features: - 8 CLK outputs @ 3.3V, up to 133.34MHz. - 1-REF output @ 3.3V, 14.31818MHz.
