CONTROL PINS (continued)
NAME
PIN
TYPE
DESCRIPTION
TXOUT1
1
CIT
Advanced Tx Control 1:
Low: Enables fixed LVPECL equalizer at the transmit inputs SIDP/N for
FR4 trace lengths up to 1.5m.
Float: Normal operation
High: Normal operation
TXOUT0
2
CIT
Advanced Tx Control 0:
Low: Nominal amplitude
Float: 5% amplitude boost
High: 10% amplitude boost
TXPD
12
CID
Transmitter Power Down:
When high, powers down and tri-states the transmit driver. The transmit
monitor port, if enabled, is also powered down when TXPD is high.
SPSL
58
CID
Serial Port Selection:
When high, chip is software controlled through the serial port.
CKSL
62
CIT
Reference Clock Frequency Selection:
Selects the reference frequency that is supplied at the CKREFP/N pins. Its level
is read in only at power-up or on the rising edge of a reset signal at the PORB
pin.
Low: 19.44MHz or 17.408MHz
Float: 77.76MHz
High: 155.52MHz or 139.264MHz
