Flexible Clock Translator for GPON, Base Station, SONET/SDH, T1/E1, and Ethernet
The AD9553 is pin programmable, providing a matrix of standard input/output frequency translations from a list of 15 possible input frequencies to a list of 52 possible output frequency pairs (OUT1 and OUT2). The device also has a 3-wire SPI interface, enabling the user to program custom input-to-output frequency translations.
The AD9553 output is compatible with LVPECL, LVDS, or single-ended CMOS logic levels, although the AD9553 is implemented in a strictly CMOS process.
The AD9553 operates over the extended industrial temperature range of −40°C to +85°C.
