The device has an integrated serial clock and data-recovery (CDR) circuit, loss-of-signal (LOS) detection circuitry as well as an advanced feature set including performance monitoring and a serial interface (2-wire or 4-wire) for register access. The BCM8228 reference clock input frequency is user-selectable to the line rate divided by either 16 or 10. It can be powered with a single 1.8V supply or dual 1.8V/3.3V supply without any special power-supply sequencing requirements. Power consumption of the device is typically 1.1W. The Power-Down Control register turns off any unused blocks. The BCM8228 is packaged in a 15-mm x 15-mm, 196-pin BGA. The BCM8228 provides high jitter tolerance and low jitter generation to comply with Optical Internetworking Forum (OIF), IEEE 802.3, Telcordia, ANSI, and ITU-T standards.
