Product details
Overview
SY10EL07ZC from Micrel is a 2-input ECL XOR/XNOR gate in 8-pin SOIC (Z8-1) package, featuring 260 ps typical propagation delay, 225 ps typical output rise/fall time (20%–80%), and internal 75 kΩ input pull-down resistors. It operates with VEE = –5.2 V and VCC = GND, targeting high-speed logic in telecom clock distribution and differential data path conditioning.
For engineers reviewing the SY10EL07ZC datasheet, SY10EL07ZC pinout, SY10EL07ZC application, or SY10EL07ZC equivalent, key selection factors include its ECL-compatible differential I/O, commercial temperature range (0°C to +70°C), SOIC-8 footprint, and functional equivalence to industry-standard E107 logic with enhanced AC performance.
Technical Context
The SY10EL07ZC implements true dual-output (Q and Q̅) ECL logic with complementary XOR and XNOR functions on a single die. Its internal 75 kΩ pull-downs eliminate external biasing for unterminated inputs, and it requires negative supply (VEE = –4.75 V to –5.5 V) referenced to VCC = GND.
Designed for 100 Ω terminated transmission lines, the device delivers sub-300 ps propagation delay across temperature and supports DC-coupled differential signaling without level-shifting circuitry-enabling direct interface with other ECL/PECL devices in clock/data recovery paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | ECL (Emitter-Coupled Logic), compatible with 100K-series standards |
| Propagation Delay (tPD) | 260 ps typical - enables >3 GHz toggle rate in closed-loop timing paths |
| Output Rise/Fall Time | 225 ps typical (20%–80%) - supports clean edge integrity on 100 Ω PCB traces |
| Supply Voltage (VEE) | –5.2 V nominal (–4.75 V to –5.5 V) - requires negative rail regulation |
| Input Pull-down | 75 kΩ internal - eliminates need for external bias resistors on D0/D1 |
| Operating Temperature | 0°C to +70°C - commercial-grade thermal envelope for non-industrial systems |
| Package | 8-pin SOIC (Z8-1, .150" wide) - standard surface-mount footprint with NC pins at 1 and 8 |
Pinout & Package
SY10EL07ZC is housed in an 8-pin SOIC (Z8-1) package with 0.150" body width and Sn-Pb lead finish. Pins 1 and 8 are no-connect (NC); D0 and D1 accept differential or single-ended ECL inputs; Q and Q̅ provide complementary outputs; VCC is tied to ground; VEE supplies the negative rail.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | No Connect (NC) | Unbonded; must remain unconnected per datasheet - no routing or grounding |
| 2 (D1) | Data Input 1 | Differential input with internal 75 kΩ pull-down to VEE - accepts ECL logic levels |
| 3 (VCC) | Ground Reference | Connected to system ground (0 V); not a power supply pin |
| 4 (Q) | XOR Output | True output of D0 ⊕ D1; ECL-compatible swing referenced to VEE |
| 5 (VEE) | Negative Supply | –5.2 V supply rail; must be decoupled locally to minimize noise coupling |
| 6 (Q̅) | XNOR Output | Complementary output of D0 ⊙ D1; matches Q timing within 20 ps skew |
| 7 (D0) | Data Input 0 | Primary differential input with internal 75 kΩ pull-down - identical to D1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary outputs | Simultaneous XOR (Q) and XNOR (Q̅) outputs reduce external logic count in phase detection |
| 75 kΩ internal input pull-downs | Eliminates two external 75 kΩ resistors per input - simplifies layout and improves signal integrity |
| 260 ps typical propagation delay | Enables use in <300 ps jitter budget systems such as SONET/SDH framers and retimers |
| 225 ps output transition time | Meets 100 Ω transmission line requirements without added termination complexity |
| ECL-compatible I/O | Direct interface with MC100EP, SY100EL, and other 100K-series logic without level shifters |
Applications
| Telecom Clock Distribution | High-Speed Data Multiplexing |
|---|---|
Use Scenario: Distributing synchronized clock signals across multiple ASICs in OC-48 line cards with minimal skew. IC Role / Device Role / Timing Role: XOR/XNOR gate used in clock phase alignment and glitch-free multiplexer control. Use Value: 260 ps tPD and matched Q/Q̅ skew enable sub-500 ps channel-to-channel skew control in fanout networks. | Use Scenario: Selecting between two high-speed serial data streams (e.g., primary/backup SONET paths) in real time. IC Role / Device Role / Timing Role: Dual-output logic element generating select and inverse-select control for differential MUX drivers.

IC Role / Device Role / Timing Role: XOR-based phase detector generating UP/DOWN pulses proportional to phase difference. Use Value: Matched Q/Q̅ propagation delays (<20 ps skew) ensure symmetrical charge pump current - minimizing static phase offset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR/XNOR logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100EP07DTG | PECL family; VCC = +3.3 V, VEE = GND; 220 ps tPD; no internal pull-downs | Requires external 50 Ω Thevenin termination; higher supply voltage simplifies mixed-signal board design | Choose when migrating to PECL infrastructure or needing lower power at 3.3 V operation |
| SY100EL07ZC | Same pinout and function; 100EL variant rated for wider temp range (–40°C to +85°C); identical AC specs | Industrial temperature support enables deployment in base station outdoor units | Choose SY100EL07ZC if extended temperature operation or long-term industrial qualification is required |
Compared with SY10EL07ZC, MC100EP07DTG shifts supply architecture to positive-rail PECL and removes internal pull-downs-increasing BOM count but easing compatibility with modern 3.3 V systems; SY100EL07ZC retains identical functionality and pinout while extending thermal range, making it a drop-in upgrade for harsher environments.

FAQ
What is the recommended power supply configuration for SY10EL07ZC?
The SY10EL07ZC requires a negative supply: VEE = –5.2 V (–4.75 V to –5.5 V) and VCC = 0 V (ground). Decoupling capacitors (e.g., 0.1 µF ceramic + 10 µF tantalum) must be placed near pin 5 (VEE) and pin 3 (VCC). No positive supply voltage is used - VCC is a ground reference only. This configuration ensures proper ECL biasing and meets the 260 ps propagation delay spec of SY10EL07ZC.
Does SY10EL07ZC support single-ended input operation?
Yes, SY10EL07ZC supports single-ended inputs via its internally pulled-down D0 and D1 pins (75 kΩ to VEE). When one input is held static (e.g., D1 = LOW), the device functions as an inverter or buffer depending on the other input state. However, full AC performance (260 ps tPD, 225 ps tr/tf) is guaranteed only under differential or properly terminated single-ended conditions per the SY10EL07ZC datasheet.
Are pins 1 and 8 of SY10EL07ZC required to be left floating?
Yes - pins 1 and 8 of SY10EL07ZC are designated NC (No Connect) and must remain unconnected. The die does not bond these pins; routing traces, solder pads, or vias to them may cause parasitic coupling or mechanical stress. Micrel's datasheet explicitly prohibits connecting or grounding pins 1 and 8, and doing so voids the guaranteed 260 ps propagation delay and 225 ps transition time specs of SY10EL07ZC.
How does SY10EL07ZC differ from SY100EL07ZC?
SY10EL07ZC is rated for commercial temperature range (0°C to +70°C), while SY100EL07ZC extends to –40°C to +85°C. Both share identical pinout, AC specs (260 ps tPD, 225 ps tr/tf), and internal 75 kΩ pull-downs. The "100" prefix denotes industrial qualification - SY100EL07ZC undergoes additional screening and is preferred for base stations or avionics where SY10EL07ZC would not meet thermal reliability requirements.
Can SY10EL07ZC drive 50 Ω transmission lines directly?
No - SY10EL07ZC is designed for 100 Ω differential or 50 Ω Thevenin-terminated single-ended loads. Driving a bare 50 Ω line causes impedance mismatch, signal reflection, and degraded 225 ps output transition time. For 50 Ω systems, use series or parallel termination per the SY10EL07ZC application guidelines, or select a PECL variant like MC100EP07DTG optimized for 50 Ω source termination.
