This document describes the functions and usage of a pair of boards. If you want to check the operation immediately,
see 1.3 Quick Start Guidelines. Communication at a data rate of about 600Mbps is established.
* DC power supply, four SMA coaxial cables or four SMA connectors, and jumper pins must be prepared.

1.3 Quick start guide
1.3.1 Connect the master and slave boards with jumper pin settings as shown in Figure 3 using SMA coaxial cables.
1.3.2 When DC3.3V is supplied to the power supply terminals of both boards, the LED of D1 lights up. The master
board THCS252 internal oscillator starts operating at 20MHz and outputs a downlink signal. When this signal is
received by THCS252 of the slave board and the internal circuit is locked, an uplink signal is output. When this signal
is received by THCS252 of the master board and the internal circuit is locked, communication between the master
and slave is established. When communication is established, THCS252 READY = H and D2 LED lights.
1.3.3. In this state, the built-in oscillator 20MHz operates as the sampling clock, and serialization of 30 times.
Communication is performed at a speed of 600Mbps for both downlink and uplink.
* Since this is an internal
oscillator of the LSI, the sampling clock and transmission rate may vary up to +/- 20%.
