Product details
Overview
SY10EP01VZC-TR from Micrel is a 4-input ECL OR/NOR gate operating at 3.3V or 5V supply, delivering 230ps typical propagation delay, 3GHz maximum toggle frequency, and differential Q and /Q outputs with internal 75kΩ input pulldowns-used in high-speed clock distribution and logic decision circuits in telecom line cards.
For engineers reviewing the SY10EP01VZC-TR datasheet, SY10EP01VZC-TR pinout, SY10EP01VZC-TR application, or SY10EP01VZC-TR equivalent, key selection criteria include ECL-compatible voltage thresholds (VIH = –1.21V min, VIL = –1.935V max), output drive capability (±50mA continuous), thermal stability across –40°C to +85°C, and SOIC-8 package compatibility with high-density PCB layouts.
Technical Context
The SY10EP01VZC-TR implements true ECL logic with dual complementary outputs (Q and /Q) referenced to either VCC or VEE depending on supply configuration (VCC = 0V/VEE = –5.5V or VCC = +3.3V/+5.5V/VEE = 0V). Its differential output structure supports 50Ω termination to VCC – 2.0V, enabling clean signal integrity up to 3GHz.
Input pins D0–D3 feature 75kΩ internal pulldown resistors, ensuring Q defaults LOW when inputs are open-a critical fail-safe behavior for unconnected control paths. Propagation delay variation (tSKEW ≤ 20ps) and matched rise/fall times (tr/tf = 60–180ps) support precise timing alignment in parallel data paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL logic gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC10EP01DTG | Same 4-input OR/NOR function, but in 8-pin TSSOP; VOH/VOL tighter (–0.92V/–1.72V typ), tPD slightly faster (140ps typ) | Requires different land pattern; better suited for space-constrained RF modules | Select MC10EP01DTG when board area is constrained and tighter DC specs are required |
| SN65EPT23DR | 3.3V-only LVPECL gate with integrated 50Ω termination; no negative supply support; lower power (18mA IEE) | Limited to single-supply systems; not suitable for legacy –5.2V ECL backplanes | Select SN65EPT23DR only for new 3.3V LVPECL designs where supply simplification outweighs backward compatibility needs |
Compared with MC10EP01DTG and SN65EPT23DR, the SY10EP01VZC-TR uniquely supports dual-supply operation (±5.5V or +3.3V/+5.5V), retains full compatibility with legacy ECL-10K infrastructure, and delivers robust open-input behavior via internal pulldowns-making it the preferred choice for mixed-voltage telecom upgrades.

FAQ
What supply configurations does the SY10EP01VZC-TR support?
The SY10EP01VZC-TR supports two mutually exclusive supply modes: (1) VCC = 0V and VEE = –3.0V to –5.5V for traditional negative-rail ECL operation, or (2) VCC = +3.3V or +5.5V and VEE = 0V for positive-rail PECL-compatible use. Both modes deliver identical logic function and timing performance. The SY10EP01VZC-TR datasheet specifies DC and AC parameters under both conditions, with output loading defined as 50Ω to VCC – 2.0V in each case.
Does the SY10EP01VZC-TR require external pull-down resistors on its inputs?
No, the SY10EP01VZC-TR integrates 75kΩ internal pulldown resistors on each D0–D3 input, ensuring predictable LOW default state on Q when inputs are left unconnected or unterminated. This eliminates the need for discrete external biasing components and reduces BOM count and layout complexity. The SY10EP01VZC-TR maintains this behavior across its full operating temperature range (–40°C to +85°C) and supply voltages.
What is the guaranteed maximum propagation delay for the SY10EP01VZC-TR?
The SY10EP01VZC-TR guarantees a maximum propagation delay (tPD) of 300ps over temperature (–40°C to +85°C) and supply variations, with typical performance of 230ps at +25°C. This value applies to the path from any input (D0–D3) to either Q or /Q output under loaded conditions (50Ω to VCC – 2.0V). The SY10EP01VZC-TR datasheet confirms tPD is measured differentially to minimize common-mode noise impact.
Can the SY10EP01VZC-TR drive multiple ECL loads directly?
Yes-the SY10EP01VZC-TR provides ±50mA continuous output current per Q or /Q pin, sufficient to drive up to three standard 50Ω ECL loads (each drawing ~20mA) simultaneously while maintaining VOH ≥ –0.885V and VOL ≤ –1.685V. Its output stage is designed for direct 50Ω transmission-line termination without external series resistors, preserving signal integrity up to 3GHz. The SY10EP01VZC-TR's output drive strength is validated across its full commercial temperature range.
Is the SY10EP01VZC-TR pin-compatible with older Micrel ECL gates like the SY100EP01?
No-the SY10EP01VZC-TR is not pin-compatible with the SY100EP01 due to differing pin assignments: SY10EP01VZC-TR places VCC on pin 8 and VEE on pin 5, whereas SY100EP01 uses pin 8 for VEE and pin 1 for VCC. Additionally, the SY10EP01VZC-TR features internal input pulldowns absent in SY100EP01. While functionally equivalent as a 4-input OR/NOR gate, PCB redesign is required to migrate from SY100EP01 to SY10EP01VZC-TR.
