SINGLE-CHANNEL T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
REV. 1.0.1
With TDQRSS activated, a bit error can be inserted in the transmitted QRSS pattern by transitioning the
INSBER interface bit from “0” to “1”. Bipolar violation can also be inserted either in the QRSS pattern, or input
data when operating in the single-rail mode by transitioning the INSBPV interface bit from “0” to “1”. The state
of INSBER and INSBPV bits are sampled on the rising edge of the TCLK. To insure the insertion of the bit error
or bipolar violation, a “0” should be written in these bit locations before writing a “1”.
