Equalizer Bit 1: MSB of equalizer setting.
Equalizer Bit 0: LSB of equalizer setting. Equalization
is as follows for 34 Mbit/s operation:
EQB1
* f = 1/2 the bit rate
Transmit AIS: When TXAIS is low, the MRT sends an
AIS (all ones signal) for the line side transmit output
data. The terminal side transmit data path is disabled.
The reference clock (DCK) provides the clock required
for generating AIS.
Voltage Controlled Oscillator Capacitor: For 6, 8,
and 34 Mbit/s operation, a 470
tor is connected in series with a 0.1 F
tor to ground. These components are used in the
phase-locked loop filter.
Phase-Locked Loop Capacitor: 0.1 F
ceramic disk capacitor connected to ground.
Automatic Gain Filter: For 6/8 MHz mode, 0.01 F
10% ceramic disk capacitor connected to ground. For
34 Mbit/s mode, open.
