IDT MPC962309EJ-1H Low-cost, 3.3v zero delay buffer Datasheet

Low-Cost, 3.3V Zero Delay Buffer
NRND – Not Recommend for New Designs
DATASHEET
The MPC962309 is a zero delay buffer designed to distribute high-speed
clocks. Available in a 16-pin SOIC or TSSOP package, the device accepts one
reference input and drives nine low-skew clocks. The MPC962305 is the 8-pin
version of the MPC962309 which drives five outputs with one reference input.
The -1H versions of these devices have higher drive than the -1 devices and can
operate up to 100/-133 MHz frequencies. These parts have on-chip PLLs which
lock to an input clock presented on the REF pin. The PLL feedback is on-chip and
is obtained from the CLOCKOUT pad.

The MPC962309 has two banks of four outputs each, which can be controlled by the Select Inputs as shown in Table 3. Bank
B can be tri-stated if all of the outputs are not required. Select inputs also allow the input clock to be directly applied to the outputs
for chip and system testing purposes.
The MPC962305 and MPC962309 PLLs enters a power down state when there are no rising edges on the REF input. During
this state, all of the outputs are in tristate, the PLL is turned off, and there is less than 25.0 A of current draw for the device. The
PLL shuts down in one additional case as shown in Table 3.
Multiple MPC962305 and MPC962309 devices can accept the same input clock and distribute it throughout the system. In this
situation, the difference between the output skews of two devices will be less than 700 ps.
All outputs have less than 200 ps of cycle-cycle jitter. The input-to-output propagation delay on both devices is guaranteed to
be less than 350 ps and the output-to-output skew is guaranteed to be less than 250 ps.
The MPC962305 and MPC962309 are available in two/three different configurations, as shown on the ordering information
page. The MPC962305-1/MPC962309-1 are the base parts. High drive versions of those devices, MPC962305-1H and
MPC962309-1H, are available to provide faster rise and fall times of the base device.
