For those designs requiring the AAL1GATOR-4, it is possible to design schematics such that both the pin-compatible AAL1GATOR-8 and AAL1GATOR-4 can be populated in the same socket. What this allows is the use of the AAL1GATOR-8 for test and debugging purposes in the lab. For production boards, the AAL1GATOR-4, once available, can simply be populated in place of the AAL1GATOR-8. To design a printed circuit board for the PM73123 AAL1GATOR-8 that is forwardcompatible to the PM73124 (AAL1GATOR-4) requires a minimum of preparations. The preparations are divided into hardware considerations and software considerations.

The AAL1GATOR-4 is a pin-compatible version of the AAL1GATOR-8 with support for four DS1/E1 links or a single DS3/E3 link. While AAL1GATOR-8 supports 256 VCs and 2 H-MVIP links, AAL1GATOR-4 supports 128 VCs and 1 H-MVIP link. Both devices provide access to a 128k x 16 (18)- bit 10ns Synchronous SRAM or ZBT RAM and support a 52 MHz 16-bit UTOPIA L2 interface. For more information about the AAL1GATOR-8 and AAL1GATOR-4 devices, please refer to the documents listed in Section 5, References.

Ground all package balls which are inputs that are present on the AAL1GATOR-8 but are not present on the AAL1GATOR-4: * * RL_CLK(4-7), RL_SYNC(4-7), RL_DATA(4-7), RL_SIG(4-7), TL_SYNC(4-7). TL_CLK(4-7) (If TL_CLK(0-3) are configured as inputs by TLCLK_OE asserted low.) 2. Leave unconnected all package balls which are outputs that are unused on the AAL1GATOR-8 but are not present on the AAL1GATOR-4: * * TL_DATA(4-7), TL_SIG(4-7). TL_CLK(4-7) (If TL_CLK(0-3) are configured as outputs by TLCLK_OE asserted high.)

The JTAG ID Code is x3123 for the AAL1GATOR-8 and x3124 for the AAL1GATOR-4. AAL1GATOR-8 requires a different JTAG BSDL file than AAL1GATOR-4.
