Freescale Semiconductor, Inc. MOTOROLA Order number: MPC962308 Rev 3, 08/2004 SEMICONDUCTOR TECHNICAL DATA 3.3 V Zero Delay Buffer The MPC962308 is a 3.3 V Zero Delay Buffer designed to distribute high-speed clocks in PC, workstation, datacom, telecom and other high-performance applications. The MPC962308 uses an internal PLL and an external feedback path to lock its low-skew clock output phase to the reference clock phase, providing virtually zero propagation delay. The input-to-output skew is guaranteed to be less than 250 ps and output-to-output skew is guaranteed to be less than 200 ps. MPC962308 Features Freescale Semiconductor, Inc... • • • • • • • • • • • • • • • 1:8 outputs LVCMOS zero-delay buffer Zero input-output propagation delay, adjustable by the capacitive load on FBK input Multiple Configurations, see Table 2. Available MPC962308 Configurations Multiple low-skew outputs 200 ps max output-output skew 700 ps max device-device skew Two banks of four outputs, output tristate control by two select inputs Supports a clock I/O frequency range of 10 MHz to 133 MHz Low jitter, 200 ps max cycle-cycle (-1, -1H, -4, -5H) ±250 ps static phase offset (SPO) 16-pin SOIC package or 16-pin TSSOP package Single 3.3 V supply Ambient temperature range: –40°C to +85°C Compatible with the CY2308 and CY23S08 Spread spectrum compatible D SUFFIX 16-LEAD SOIC PACKAGE CASE 751B-05 DT SUFFIX 16-LEAD TSSOP PACKAGE CASE 948F-01 Functional Description The MPC962308 has two banks of four outputs each which can be controlled by the select inputs as shown in Table 1. Select Input Decoding. Bank B can be tristated if all of the outputs are not required. The select inputs also allow the input clock to be directly applied to the output for chip and system testing purposes. The MPC962308 PLL 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 and there is less than 50 µA of current draw. The PLL shuts down in two additional cases explained in Table 1. Select Input Decoding. Multiple MPC962308 devices can accept and distribute the same input clock throughout the system. In this situation, the difference between the output skews of two devices will be less than 700 ps. The MPC962308 is available in five different configurations as shown in Table 2. Available MPC962308 Configurations. In the MPC962308-1, the reference frequency is reproduced by the PLL and provided at the outputs. A high drive version of this configuration, the MPC962308-1H, is available to provide faster rise and fall times of the device. The MPC962308-2 provides 2X and 1X the reference frequency at the output banks. In addition, the MPC962308-3 provides 4X and 2X the reference frequency at the output banks. The output banks driving the feedback will determine the different configurations of the above devices. The MPC962308-4 provides outputs 2X the reference frequency.The MPC962308-5H is a high drive version with outputs of REF/2. The MPC962308 is fully 3.3 V compatible and requires no external components for the internal PLL. All inputs accept LVCMOS signals while the outputs provide LVCMOS compatible levels with the capability to drive terminated 50 Ω transmission lines on the incident edge. Depending on the configuration, the device is offered in a 16-lead SOIC or 16-lead TSSOP package. © Motorola, Inc. 2004 For More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.
