ESCRIPTION
The 843022 is a Gigabit Ethernet Clock Generator and a
member of the HiPerClocks
TM
family of high performance
devices from IDT. The 843022 uses a 25MHz crystal to
synthesize 125MHz or 62.5MHz. The 843022 has excel-
lent phase jitter performance, over the 1.875MHz – 20MHz
integration range. The 843022 is packaged in a small 8-pin TSSOP,
making it ideal for use in systems with limited board space.

How can I expand external large-capacity SRAM via EMI interface of STR912?
I looked at the data sheet: 8-bit non-multiplexed mode has only 16-bit address, which means it can only expand 64KB. And 16-bit data/address multiplexing mode has 24-bit address, which means it can ex...
