Product details
Overview
IDT74FCT3807DPYI from Integrated Device Technology is a 3.3V CMOS 1-to-10 low-skew clock driver in 20-pin SSOP package, featuring <100ps max output pin-to-pin skew, <2ns max propagation delay, and 166MHz max input frequency. It delivers TTL-compatible I/O, 1:10 fanout, and operates across –40°C to +85°C for industrial clock distribution networks.
For engineers reviewing the IDT74FCT3807DPYI datasheet, IDT74FCT3807DPYI pinout, IDT74FCT3807DPYI application, or IDT74FCT3807DPYI equivalent, key selection criteria include output skew tolerance, fanout scalability, supply voltage margin (3.3V ±0.3V), and compatibility with mixed-voltage (3.3V/5V) driving sources in timing-critical systems.
Technical Context
The IDT74FCT3807DPYI implements a single-input, ten-output buffered clock distribution architecture with fully buffered outputs and independent power/ground pairs per output group to minimize switching noise coupling. Its advanced CMOS process ensures TTL-compatible input thresholds and rail-to-rail output swing under 3.3V supply.
It supports high-speed operation up to 166MHz with guaranteed pulse skew <250ps and part-to-part skew <550ps. Input drive capability includes 3.3V or 5V logic levels, while output drive strength is specified at ±75mA (OH) / +92mA (OL) at 1.5V.
Key Specifications

| Max Output Skew | <100ps (tSK(O)) - ensures synchronous edge alignment across all 10 outputs under identical load |
| Propagation Delay | <2ns (tPLH/tPHL, 3807E grade) - enables sub-2ns clock path budgeting in high-frequency designs |
| Input Frequency | Up to 166MHz - supports PCIe Gen1, DDR2 system clocks, and industrial microcontroller timing |
| Output Drive | –75mA (IOH), +92mA (IOL) at VO = 1.5V - drives 15pF loads with <1ns rise/fall times |
| Operating Temp | –40°C to +85°C - qualified for industrial control, motor drives, and base station timing modules |

Pinout & Package
Package: 20-pin Shrink Small Outline Package (SSOP), body width 5.3mm, pitch 0.65mm, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for output group 1 (O1–O4); decoupling critical for noise isolation |
| 2 | VCC | Power supply for output group 1; requires local 0.1µF ceramic bypass |
| 3 | GND | Ground reference for output group 2 (O5–O8) |
| 4 | VCC | Power supply for output group 2 |
| 5 | GND | Ground reference for input and output group 3 (O9–O10, IN) |
| 6 | GND | Additional ground for input/output section; reduces common-mode noise |
| 7 | VCC | Power supply for input buffer and output group 3 |
| 8 | GND | Ground return for O5; dedicated GND improves O5 signal integrity |
| 9 | O5 | Output 5 - one of ten buffered clock outputs; electrically isolated by adjacent GND/VCC |
| 10 | VCC | Power for output group 3 (O9–O10); separate VCC minimizes cross-talk |
| 11 | IN | Single-ended clock input - accepts 3.3V or 5V logic; internal clamping diodes protect against overvoltage |
| 12 | O1 | Output 1 - first of ten low-skew outputs; routed with matched trace length in layout |
| 13 | O2 | Output 2 - paired with O1 for differential-like routing in single-ended systems |
| 14 | O3 | Output 3 - shares power/ground pair with O1–O4; grouped for simultaneous switching control |
| 15 | O4 | Output 4 - final output in first group; GND/VCC sandwich reduces EMI emission |
| 16 | O10 | Output 10 - last output; placed near corner for shortest trace to load |
| 17 | O9 | Output 9 - second output in third group; benefits from dedicated VCC/GND pair |
| 18 | O8 | Output 8 - final output in second group; adjacent GND suppresses crosstalk |
| 19 | O7 | Output 7 - routed with O6–O8; shared VCC/GND improves group timing consistency |
| 20 | O6 | Output 6 - middle output in second group; symmetric placement aids layout symmetry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar clock driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MC100EP131DG | ECL-based, 3.3V supply, 1:9 fanout, <35ps skew, requires negative VEE and level translation | Suitable for ultra-low-jitter RF and optical comms; not drop-in due to ECL interface and biasing | Select when sub-50ps skew and <1GHz bandwidth are required; redesign needed for power and I/O |
| TI CDCVF310PWR | LVCMOS, 3.3V, 1:10 fanout, <250ps skew, integrated PLL, no 5V-tolerant inputs | Used where clock multiplication or jitter cleanup is needed; lacks mixed-voltage input support | Choose when PLL-based jitter attenuation is required; avoid if interfacing with 5V microcontrollers |
Compared with IDT74FCT3807DPYI, the MC100EP131DG offers lower skew but demands ECL infrastructure, while the CDCVF310PWR adds PLL functionality at the cost of 5V input compatibility and higher skew-making IDT74FCT3807DPYI optimal for robust, mixed-voltage, low-cost industrial clock fanout.

FAQ
What is the maximum operating frequency supported by the IDT74FCT3807DPYI?
The IDT74FCT3807DPYI supports an input frequency up to 166MHz, as confirmed in the "SWITCHING CHARACTERISTICS OVER OPERATING RANGE - 3807E" table. This specification applies under industrial temperature conditions (–40°C to +85°C), VCC = 3.3V ±0.3V, and CL = 15pF. The IDT74FCT3807DPYI achieves this using advanced CMOS process technology and optimized output buffering, making it suitable for DDR2-800 and high-speed microcontroller clocking applications.
Does the IDT74FCT3807DPYI support 5V-tolerant inputs?
Yes, the IDT74FCT3807DPYI supports 5V-tolerant inputs: its absolute maximum input voltage is –0.5V to +5.5V, and DC electrical characteristics confirm VIH up to 5.5V and VIL down to –0.5V. This allows direct interfacing with legacy 5V logic without level shifters. The IDT74FCT3807DPYI maintains TTL-compatible thresholds and includes internal clamp diodes (VIK = –0.7V to –1.2V) for overvoltage protection.
What is the pin-to-pin output skew specification for the IDT74FCT3807DPYI?
The IDT74FCT3807DPYI has a maximum same-device output pin-to-pin skew (tSK(O)) of <100ps, as specified for the "3807E" speed grade in the switching characteristics table. This value is measured between any two outputs under identical transitions and load conditions (CL = 15pF). The IDT74FCT3807DPYI achieves this via matched internal routing and dedicated power/ground pairs per output group, ensuring deterministic timing in multi-sink clock trees.
Which package type does the IDT74FCT3807DPYI use, and what are its mechanical dimensions?
The IDT74FCT3807DPYI uses a 20-pin Shrink Small Outline Package (SSOP), denoted by the "PY" suffix in the ordering code. Per IDT's ordering information, PY indicates SSOP – Green. Its JEDEC MO-153-compliant footprint has a body width of 5.3mm, lead pitch of 0.65mm, and total length of 7.2mm. The IDT74FCT3807DPYI's SSOP package supports standard reflow profiles and is compatible with automated PCB assembly processes.
How many independent power and ground connections does the IDT74FCT3807DPYI have, and why are they used?
The IDT74FCT3807DPYI has three VCC pins and four GND pins, distributed across the 20-pin SSOP to isolate output groups (O1–O4, O5–O8, O9–O10) and the input stage. This architecture minimizes simultaneous switching noise coupling between groups, directly improving output skew and jitter performance. Each VCC/GND pair serves a defined functional block, and the IDT74FCT3807DPYI datasheet emphasizes that multiple power/grounds reduce noise in clock distribution networks.
