Description
The 841S104I-02 is a PLL-based clock synthesizer specifically designed for Ethernet and SONET™ Clock applications. This device generates either a 156.25MHz or 155.52MHz differential HCSL clock from an input reference of either 25MHz or 19.44MHz. The input reference may be derived from an external source or by the addition of a 25MHz or a 19.44MHz crystal to the on-chip crystal oscillator. An external reference may be applied to the XTAL_IN pin with the XTAL_OUT pin left floating. An I2C bus interface is used to enable or disable each individual clock output. The 841S104I-02 is available in a lead-free 24-Lead package.
