TTL
Transmit Parallel Input Data
. Transmit data from an Overhead
Terminator at parallel speed 19.44 MHz, clocked in by TPICLK. TPID7 is
the most significant bit, and is the first bit to be sent. These pins should
be grounded or not connected when the LXT6155 is used in serial mode.
Transmit Trim Controls
, in serial, hardware, coax mode only. These
pins trim the amplitude of the line driver output from (nom -21%) to (nom
+24%) in 3% steps. This feature is only enabled when pin #20
(TXTRIMENA) is High.

Transmit Parallel Input Data
. Transmit data from an Overhead
Terminator at parallel speed 19.44 MHz, clocked in by TPICLK. TPID7 is
the most significant bit, and is the first bit to be sent. These pins should

Transmit Trim Enable
, in serial, hardware, coax mode only. This pin
enables the trimming of the line driver output by pins 16-19 when high.
