CY7B995 General Description

The CY7B995 RoboClock® is a low-voltage, low-power, eight-output, 200-MHz clock driver. It features output phase programmability which is necessary to optimize the timing of high-performance computer and communication systems.

The user can program both the frequency and the phase of the output banks through nF[0:1] and DS[0:1] pins. The adjustable phase feature allows the user to skew the outputs to lead or lag the reference clock. Any one of the outputs can be connected to feedback input to achieve different reference frequency multiplication and divide ratios and zero input-output delay.

The device also features split output bank power supplies which enable the user to run two banks (1Qn and 2Qn) at a power supply level different from that of the other two banks (3Qn and 4Qn). Additionally, the three-level PE/HD pin controls the synchronization of the output signals to either the rising or the falling edge of the reference clock and selects the drive strength of the output buffers. The high drive option (PE/HD = MID) increases the output current from ± 12 mA to ± 24 mA.
