The ICS87016 is a low skew, 1:16 LVCMOS/LVTTL Clock
Generator. The device has 4 banks of 4 outputs and each
bank can be independently selected for ÷1 or ÷2 frequency
operation. Each bank also has its own power supply pins so
that the banks can operate at the following different voltage
levels: 3.3V, 2.5V, and 1.8V. The low impedance LVCMOS/
LVTTL outputs are designed to drive 50Ω series or parallel
terminated transmission lines.
The divide select inputs, DIV_SELA:DIV_SELD, control the
output frequency of each bank. The output banks can be
independently selected for ÷1 or ÷2 operation. The bank enable
inputs, CLK_ENA:CLK_END, support enabling and disabling
each bank of outputs individually. The CLK_ENA:CLK_END
circuitry has a synchronizer to prevent runt pulses when
enabling or disabling the clock outputs. The master reset
input, nMR/OE, resets the ÷1/÷2 flip flops and also controls the
active and high impedance states of all outputs. This pin has
an internal pull-up resistor and is normally used only for test
purposes or in systems which use low power modes.
The ICS87016 is characterized to operate with the core at
3.3V and the banks at 3.3V, 2.5V, or 1.8V. Guaranteed bank,
output, and part-to-part skew characteristics make the
87016 ideal for those clock applications demanding
well-defined performance and repeatability.
