Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
1Y[0–3] 2, 3, 5, 7 O Clock outputs. These outputs are low-skew copies of CLKIN. Each output has an integrated 25-Ω series damping resistor.
CLKIN 1 I Clock input. CLKIN provides the clock signal to be distributed by the CDCVF2505 clock driver. CLKIN is used to provide the reference signal to the integrated PLL that generates the clock output signals. CLKIN must have a fixed frequency and fixed phase for the PLL to obtain phase lock. Once the circuit is powered up and a valid signal is applied, a stabilization time (100 µs) is required for the PLL to phase lock the feedback signal to CLKIN.
CLKOUT 8 O Feedback output. CLKOUT completes the internal feedback loop of the PLL. This connection is made inside the chip and an external feedback loop should NOT be connected. CLKOUT can be loaded with a capacitor to achieve zero delay between CLKIN and the Y outputs.
GND 4 P Ground
VDD3.3V 6 P 3.3-V supply
