This document describes the changes implemented in the QuadFALC® Version 2.1 related to the previous version 1.3. All functions not mentioned in this document remain unchanged.
QuadFALC® Version 2.1 is a pin-compatible replacement of QuadFALC® Version 1.x. Severe errata of QuadFALC® Version 1.3 are fixed.
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).
