Wireless infrastructure
Test and measurement (including handheld devices)
GENERAL DESCRIPTION
The AD9553 is a phase-locked loop (PLL) based clock translator
designed to address the needs of passive optical networks (PON)
and base stations. The device employs an integer-N PLL to
accommodate the applicable frequency translation requirements.
The user supplies up to two single-ended input reference signals or
one differential input reference signal via the REFA and REFB
inputs. The device supports holdover applications by allowing the
user to connect a 25 MHz crystal resonator to the XTAL input.
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 drivers are 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.
