AM7969-125JC FAQs

1.Q: What related parts complement the Rochester Electronics TAXICHIP receiver?

A: Complementary parts include the TAXI transmitter ICs from the same series (e.g., TAXIchip™ drivers), clock recovery units, and line driver/receiver pairs for full-duplex systems.

2.Q: Does the Rochester Electronics TAXICHIP comply with any industry certification standards?

A: While specific certifications aren't listed, the device is designed to meet MIL-STD-883 for reliability and follows common industry standards for high-speed digital interfaces.

3.Q: What is the typical power dissipation of the Rochester Electronics TAXICHIP?

A: Typical power dissipation is 300mW (max) when operating at 140Mbps with 5V supply. Actual dissipation depends on data pattern and load conditions.

4.Q: What package options are available for the Rochester Electronics TAXICHIP?

A: This device is supplied in a 28-pin PLCC (Plastic Leaded Chip Carrier) package measuring 11.51x11.51mm with J-lead contacts, suitable for surface mounting.

5.Q: What are the recommended operating conditions for the Rochester Electronics TAXICHIP?

A: Recommended conditions: 4.5V-5.5V supply voltage, 0°C-70°C ambient temperature, 100Ω differential input impedance, and data rates up to 140Mbps with NRZ coding.

6.Q: What are the absolute maximum ratings for the Rochester Electronics TAXICHIP?

A: Absolute max ratings include: Supply voltage (Vcc) = 7V, input voltage = Vcc+0.5V, operating temperature = -55°C to +125°C (storage), and junction temperature = 150°C. Exceeding these may cause permanent damage.

7.Q: In what applications is the Rochester Electronics TAXICHIP typically used?

A: It's designed for high-speed data communication systems, particularly in optical networking equipment, backplane interconnects, and military/aerospace avionics where asynchronous receiver interfaces are required.

8.Q: What are the key features of the Rochester Electronics TAXICHIP receiver IC?

A: Key features include: 140Mbps data rate, 4.5V-5.5V operating voltage, Bipolar technology, single-channel receiver functionality, and industrial temperature range (0°C to 70°C).

9.Q: What is the pinout configuration of the Rochester Electronics TAXICHIP (PLCC-28 package)?

A: The TAXICHIP uses a standard 28-pin PLCC layout (11.5x11.5mm). Pin functions include differential receiver inputs (Rx±), power supply (Vcc=pin 28), ground (GND=pin 14), and data output (pin 7). Refer to the datasheet for the complete pinout diagram.
