Overview
1.1
Functional Changes
The following function has been changed:
Version status in register VSTR changed from 02
H
to 05
H
The boundary scan part number changed to 142, the boundary scan ID changed to
1. A new BSDL file is required.
The pulse mask programming (registers XPM(2:0)) has to be adjusted.
The MCLK reference clock programming (registers GCM(8:1)) has to be changed.
Variable master clock frequency function always enabled (GCM2(4) = 1).
New feature “automatic short haul/long haul adjustment” available by setting
LIM0.EQON = 1.
Additional automatic resynchronization mode for T1 (new bit: FMR2.7 = AFRS).
Additional compare status field (mode 2) in SS7 mode (new bit: CCR5.6 = CSF2).
2048 kHz synchronization interface according o ITU-T G.703 Sec. 13 (E1). For more
information refer to online Application Notes
.1.2
All severe errata of QuadFALC
Version 1.3 have been fixed. For more information
please contact your local sales office.
Correction of Errata
1.3
QuadFALC
Version 2.1 is pin-compatible with QuadFALC
Version 1.x. However,
some pin functions have been modified as detailed below:
No 5 V input levels are allowed due to technology restrictions (see
Page 24
).
The currently unused ("N.C.") pins on V1.3 devices are used as "Core Voltage
Supply" (
V
DDC
) pins and "Voltage Selection" (VSEL) pin on V2.x devices. Due to the
new technology the core voltage is 1.8 V (see
Chapter 1.5
).
Modified Pin Functions
1.4
Package
In addition to the P-TQFP-144-8 package, a P-BGA-160-1 package with a ball pitch of
1.0 mm and a size of 15 mm
×
15 mm is supported (see
Figure 4
).
1.5
Power Supply
The Version 2.1 device requires two supply voltages, 3.3 V and 1.8 V. For compatibility
reasons, it is possible to operate the device off a single 3.3 V supply, with the 1.8 V
