Product details
Overview
MPC962308DT-1H from Freescale Semiconductor is a 3.3 V LVCMOS zero-delay clock buffer with 1:8 fanout, internal PLL, and external feedback path for phase alignment. It delivers reference-frequency outputs with <250 ps input-to-output skew and <200 ps output-to-output skew, supporting 10–133 MHz clock distribution in PC and telecom backplanes.
For engineers reviewing the MPC962308DT-1H datasheet, MPC962308DT-1H pinout, MPC962308DT-1H application, or MPC962308DT-1H equivalent, key selection criteria include its high-drive (-1H) output slew rate (1 V/ns), ±250 ps static phase offset, tristate control per bank, and TSSOP-16 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The MPC962308DT-1H implements a PLL-based zero-delay architecture where the REF input locks to the FBK feedback signal, enabling near-zero propagation delay. Its dual-bank (A/B) 4-output structure supports independent tristate control via S1/S2 select inputs and bypass mode for system test.
This variant is the high-drive version of the MPC962308-1 configuration: it reproduces the reference frequency at all eight outputs while delivering faster edge rates (1.5 ns rise/fall at 30 pF) and higher drive strength (12 mA IOL/IOH), optimized for terminated 50 Ω transmission lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.3 V ±10% - single-rail operation compatible with modern low-voltage logic systems |
| Input Frequency Range | 10 MHz to 133 MHz - supports PCI, AGP, and DDR memory clocking requirements |
| Output Skew (same bank) | <200 ps - ensures timing-critical parallel bus synchronization across multiple loads |
| Rise/Fall Time | 1.5 ns / 1.25 ns at 30 pF - enables clean signal integrity on high-speed PCB traces |
| Static Phase Offset | ±250 ps - guarantees deterministic phase relationship between REF and FBK for stable PLL lock |

Pinout & Package
Package: 16-pin TSSOP (DT suffix), case 948F-01, 4.4 mm × 5.0 mm footprint, 0.65 mm pitch, surface-mount compatible.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | REF | 5 V-tolerant reference clock input with weak pull-down; primary PLL reference source |
| 2–5, 6–7, 10–11, 14–15 | CLKA1–CLKA4, CLKB1–CLKB4 | LVCMOS clock outputs grouped in two banks; each bank independently tristatable via S1/S2 |
| 8–9 | S2, S1 | Active-high select inputs with weak pull-ups; decode bank enable/bypass modes per Table 1 |
| 16 | FBK | PLL feedback input; connects to one output (A or B bank) to close phase-locked loop |
| 4, 13 | VDD | 3.3 V supply pins - dual power connections reduce IR drop and improve noise immunity |
| 5, 12 | GND | Ground pins - dual ground connections minimize ground bounce across output switching |
Key Features
| Feature | Design Value |
|---|---|
| High-Drive Output Stage | 12 mA sink/source capability enables direct driving of 50 Ω terminated lines without external buffers |
| Dual-Bank Tristate Control | S1/S2 inputs allow dynamic disabling of Bank A, Bank B, or both - reduces system power during idle states |
| Zero-Delay PLL Architecture | External FBK path eliminates fixed propagation delay; aligns output edges precisely to REF rising edge |
| Spread Spectrum Compatibility | Accepts spread-spectrum clock inputs without loss of lock or increased jitter - supports EMI reduction schemes |
| Power-Down Mode | Automatic entry when REF stops toggling; draws <25 µA, placing all outputs in high-impedance state |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zero-delay clock buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY2308ZC | Same 1:8 LVCMOS zero-delay architecture but rated for 10–125 MHz; no high-drive option; SOIC-only packaging | Lacks MPC962308DT-1H's 133 MHz support and TSSOP footprint; lower drive strength (8 mA) limits 50 Ω line driving | Select CY2308ZC only if operating below 125 MHz and SOIC packaging suffices |
| MPC962308D-1H | Identical electrical specs and functionality; differs only in SOIC-16 (D suffix) vs. TSSOP-16 (DT suffix) package | SOIC package offers easier prototyping and rework; TSSOP saves board area in high-density designs | Choose MPC962308D-1H for through-hole-compatible assembly or manual soldering; MPC962308DT-1H for space-constrained SMT production |
Compared with CY2308ZC and MPC962308D-1H, the MPC962308DT-1H uniquely combines 133 MHz operation, 12 mA drive, TSSOP packaging, and industrial temperature rating - making it optimal for compact, high-speed, thermally demanding clock distribution nodes.

FAQ
What is the maximum supported clock frequency for MPC962308DT-1H?
The MPC962308DT-1H supports clock frequencies up to 133.3 MHz when loaded with ≤15 pF, as confirmed in Table 7 of the Freescale datasheet. This exceeds standard 100 MHz PCI and 133 MHz AGP requirements, and is enabled by its high-drive (-1H) output stage. The MPC962308DT-1H maintains guaranteed skew and jitter performance across this full range.
Does MPC962308DT-1H require external passive components for PLL operation?
No, the MPC962308DT-1H requires no external resistors, capacitors, or crystals for PLL operation. Its internal PLL uses only the external feedback connection from an output pin to the FBK input (Pin 16). The device is fully functional with just VDD, GND, REF, FBK, and output loads - simplifying layout and reducing BOM count.
How does the tristate control work on MPC962308DT-1H?
The MPC962308DT-1H uses S1 (Pin 9) and S2 (Pin 8) to control output banks: S2=0/S1=1 enables Bank A only; S2=1/S1=0 enables Bank B only (inverted on -2 variants, not applicable here); S2=1/S1=1 enables both banks. All outputs go high-impedance when S2=S1=0. This allows dynamic clock gating per subsystem without redesigning the clock tree.
Is MPC962308DT-1H compatible with 5 V logic inputs?
Yes, the REF input (Pin 1) is explicitly 5 V tolerant per Table 4, allowing direct connection to legacy 5 V clock sources without level-shifting. All other inputs (S1, S2, FBK) operate at 3.3 V LVCMOS levels. Outputs are 3.3 V LVCMOS compatible and can drive terminated 50 Ω lines on the incident edge.
What is the static phase offset specification for MPC962308DT-1H?
The MPC962308DT-1H has a static phase offset (SPO) of ±250 ps, defined as the worst-case phase difference between the REF rising edge and the FBK rising edge at lock (Table 7, parameter t6). This tight tolerance ensures predictable phase alignment critical for synchronous system timing, especially when cascading multiple zero-delay buffers.
