TTL/ I2C / SPI Expansion Kit for Measuring the Low Voltage Signal LVTTL

LINEEYE releases the TTL/I2C/SPI expansion kit “OP-SB85L” and “OP-SB5GL” which can measure the low voltage signal such as 1.8V and 2.5V.

[ Outline ]

LINEEYE has been manufactured the TTL/ I2C/ SPI expansion kit “OP-SB85” for LE-8200 and “OP-SB5G” for LE-2500/3500 to measure TTL level communications. Nowadays, the demand of measuring low voltage signal (1.8V, 2.5V) and supporting the Push Pull OMOS output for high  speed simulation is increasing.
“OP-SB85L” and “OP-SB5GL” support the signal level of 1.8V/2.5V/3.3V/5V, and able to select the open collector output and COMS push-pull output. By using with the “OP-FW12G” and “OP-FW10G” (latest version), it can measure SPI communications at 10Mbps and test the LVTTL level high speed HDLC communications. It is useful when measuring between high-speed module and microcomputer by probing the communication lines directly.

[ Feature ]

  1. Support low voltage signal such as LVTTL/ TTL on 1.8V, 2.5V, 3.3V and 5V.
  2. Able to have the simulation test by high-speed CMOS push pull output.
  3. Use the small probe to support the narrow terminal pitch (approx. 1.27mm)
