SNLS696A April 2021 – May 2021 TSER953
The TSER953 serial data out signal operates at different data rates depending upon the mode in which the device is operating. In synchronous mode, where the reference clock is provided by the deserializer, the serial data rate is up to 4.16 Gbps.
The signals at DOUT+ and DOUT– must be AC-coupled. The AC-coupling capacitor values used on DOUT+ and DOUT– depends on the mode and cable used as shown in Table 8-3. When connecting to a coax cable, the AC-coupling capacitor on the negative terminal (DOUT–) should be approximately ½ of the AC-coupling capacitor value on DOUT+ and be terminated to a 50-Ω load. Make sure to follow the critical PCB layout guidelines given in Section 10.2.
