2 / 30 page QuadFALC® PEF 22554 Overview Delta Sheet 2/30 2002-09-16 1Overview 1.1 Functional Changes The following function has been changed: • Version status in register VSTR changed from 02H to 05H • 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 http://www.infineon.com/falc. 1.2 Correction of Errata All severe errata of QuadFALC® Version 1.3 have been fixed. For more information please contact your local sales office. 1.3 Modified Pin Functions 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" (VDDC) 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). 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 |
