Microchip Technology's SY10ELT23ZG: High-Speed Differential PECL-to-TTL Translator

The SY10ELT23ZG is a versatile integrated circuit from Microchip Technology, designed to bridge the gap between high-speed differential PECL (Positive Emitter Coupled Logic) circuits and TTL (Transistor-Transistor Logic) interfaces. This product is part of Microchip's high-performance ECLinPS MAX™ family, offering a solution for systems that require fast signal processing and translation between differing logic levels.

Constructed with advanced silicon-gate CMOS technology, the SY10ELT23ZG provides two differential PECL-to-TTL translators, which means it can convert two PECL input signals into TTL output signals. This feature is particularly useful in applications such as telecommunications, data communications, and high-speed computing where interfacing between different logic families is necessary.

The device operates over a wide voltage range, with V<sub>CC from 4.2V to 5.5V and V<sub>BB reference voltage output for single-ended PECL input signals, ensuring compatibility with a variety of TTL logic levels and providing design flexibility. The SY10ELT23ZG is capable of operating at frequencies up to 3GHz, making it suitable for high-speed applications.

Furthermore, the SY10ELT23ZG features a flow-through pinout for ease of PCB layout and minimal signal skew, which is critical in maintaining signal integrity at high speeds. The device is housed in a compact 8-pin SOIC package, which makes it space-efficient for designs where board real estate is at a premium.

Key specifications include:

• 3GHz typical maximum frequency
• 200ps typical propagation delay
• Flow-through pinout for optimal signal routing
• Internal 75kΩ input pull-down resistors
• Internal input hysteresis for improved noise margin
• Available in an 8-pin SOIC package

In summary, the SY10ELT23ZG from Microchip Technology is an essential component for designers looking to interface PECL and TTL logic levels without compromising on speed or signal integrity. Its high-speed capabilities, coupled with its ease of use and compact form factor, make it an excellent choice for a broad range of applications in the electronics industry.
