Description
The CY7B995 RoboClock
廬
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 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). The three-level PE/HD pin also controls the synchroni-
zation 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 鹵 12 mA to 鹵 24 mA.
