Pin Type Pin Description
O-PECL
In CDR at entry configuration, this pin is the Serial Output
(TO_LOOP+). In other configurations, this pin is wired to the hard disk.
O-PECL
In CDR at entry configuration, this pin is the Serial Output
(TO_LOOP–). In other configurations, this pin is wired to the hard disk.
I-PECL
Input from Transceiver IC to Cell 1.
I-PECL
Input from Transceiver IC to Cell 1.
O-PECL
Output to Transceiver IC from Cell 1.
O-PECL
Output to Transceiver IC from Cell 1.
I-PECL
In CDR at entry configuration, this pin is the Serial Input
(FM_LOOP+). In other configurations, this pin is wired to the hard disk.
I-PECL
In CDR at entry configuration, this pin is the Serial Input
(FM_LOOP–). In other configurations, this pin is wired to the hard disk.
I-LVTTL
Bypass pin for cell 1. In CDR at exit configuration, float to HIGH else
ground connect through a 1 K
resistor.
I-LVTTL
Bypass pin for cell 0. In CDR at exit configuration, float to HIGH else
ground connect through a 1 K
resistor.
I-LVTTL
Reference Clock Input for Clock and Data Recovery (CDR) circuit.
C
PLL cap pin. Connected to pin 13 with a 0.1 microFarad capacitor.
C
PLL cap pin. Connected to pin 12 with a 0.1 microFarad capacitor.
O-LVTTL
Signal Detect via envelope detect method. In CDR at entry and at exit
cases, detects signal on incoming cable respectively. Active High when
signal is detected.
If (FM_NODE[0]+ –FM_NODE[0]–) >= 400 mV peak-to-peak, SD = 1
If 400 mV >= (FM_NODE[0]+ –FM_NODE[0]–) >= 100 mV,
SD = unpredictable
If 100 mV >= (FM_NODE[0]+ –FM_NODE[0]–), SD = 0
