13 DATA SHEET REVISION HISTORY
REVISION
070105
042007
DATE
Initial release.
Added descriptions of feature enhancements implemented in revision A2:
See below for the detailed list of changes made to this data sheet revision.
See Features bullets, Detailed Description, and Section 5.5.1 for mention of fully
internal receive impedance matching.
Added RESREF pin (R9).
In OE pin description, changed GC.RTCTL to TST.RHPMC.
Deleted R9 from DVSS.
In Section 5.4: Transmitter, second paragraph, changed NRZ encoding to AMI
encoding.
Replaced Figure 5-8.
In Table 5-6, updated Rt; updated Section 5.4.3 and Section 5.4.4; in Section
5.4.5: Zero Suppression—B8ZS or HDB3, removed “or Transmit Maintenance
Register settings” from last sentence of first paragraph (no such register for this
part).
Changed Section 5.4.8 name from Drive Failure Monitor to Driver Fail Monitor;
updated Section 5.5; added new Section 5.5.1: Receive Impedance Matching
Calibration.
Added Section 5.5.8: Receive Dual-Rail Mode; added new Section 5.5.9: Receive
Single-Rail Mode; updated Table 5-11.
Updated Section 5.8.2: Digital Loopback.
Added new paragraph to Section 5.9: BERT.
Changed GMC to BGMC (Table 6-1) (see also page 53).
In Table 6-4, deleted Receive Bit Error Count Register 4 (does not exist for this
part).
In Table 6-5, changed bit names for LOSS (LIUs 1–16) to correctly match bit
description on page 49; for TST, changed bits 7–5 from Reserved to JABWS1,
JABWS0, and RHPMC (see also page 58).
In Table 6-6, changed SRS bit to correctly say SRMS.
In Table 6-7, added missing address (27) to SHLHS for LIUs 9–16; changed bit 7
and bits 3–0 names for RSMM4 (LIUs 9–16) to correctly match bit description on
page 74; changed “GISC” (3E) to “Not Used” for LIUs 9–16.
In Table 6-8, changed BSR register bit 3 (PMS) to show it is read only (added
underline), matching the bit description on page 88, as well as changed “RW” to
“R” to correctly show all bits are read only; changed BSRL register bit 3 (PMSL) to
show it is read only (added underline), matching the bit description on page 89, as
well as changed “RL/W” to “R” to correctly show all bits are read only.
1) Programmable corner frequency for the jitter attenuator in E1 mode.
2) Fully internal impedance matching option for RTIP/RRING.
3) Option for system-side deployment of BERT.
4) Revised B8ZS/HDB3 sections for clarification of functions.
5) Added RESREF pin for receive termination calibration.
