The MPC940L is a 1:18 low voltage clock distribution chip with 2.5V or
3.3V LVCMOS output capabilities. The device features the capability to
select either a differential LVPECL or an LVCMOS compatible input. The
18 outputs are 2.5V or 3.3V LVCMOS compatible and feature the drive
strength to drive 50Ω series or parallel terminated transmission lines.
With output–to–output skews of 150ps, the MPC940L is ideal as a clock
distribution chip for the most demanding of synchronous systems. The
2.5V outputs also make the device ideal for supplying clocks for a high
performance microprocessor based design. For a similar device at a
lower price/performance point the reader is referred to the MPC9109. LVPECL or LVCMOS Clock Input 2.5V LVCMOS Outputs for Pentium II Microprocessor Support 150ps Maximum Output–to–Output Skew Maximum Output Frequency of 250MHz 32–Lead LQFP Packaging Dual or Single Supply Device: Dual VCC Supply Voltage, 3.3V Core and 2.5V Output Single 3.3V VCC Supply Voltage for 3.3V Outputs Single 2.5V VCC Supply Voltage for 2.5V I/O
With a low output impedance (≈20Ω), in both the HIGH and LOW logic
states, the output buffers of the MPC940L are ideal for driving series
terminated transmission lines. With a 20Ω output impedance the 940L
has the capability of driving two series terminated lines from each output.
This gives the device an effective fanout of 1:36. If a lower output
impedance is desired please see the MPC942 data sheet.
The differential LVPECL inputs of the MPC940L allow the device to interface directly with a LVPECL fanout buffer like the
MC100EP111 to build very wide clock fanout trees or to couple to a high frequency clock source. The LVCMOS input provides a
more standard interface for applications requiring only a single clock distribution chip at relatively low frequencies. In addition, the
two clock sources can be used to provide for a test clock interface as well as the primary system clock. A logic HIGH on the
LVCMOS_CLK_Sel pin will select the LVCMOS level clock input. All inputs of the MPC940L have internal pullup/pulldown
resistor so they can be left open if unused.
The MPC940L is a single or dual supply device. The device power supply offers a high degree of flexibility. The device can
operate with a 3.3V core and 3.3V output, a 3.3V core and 2.5V outputs as well as a 2.5V core and 2.5V outputs. The 32–lead
LQFP package was chosen to optimize performance, board space and cost of the device. The 32–lead LQFP has a 7x7mm body
size with a conservative 0.8mm pin spacing.
