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.

FEATURES

Input frequencies from 8 kHz to 710 MHz

Output frequencies up to 810 MHz LVPECL and LVDS (up to

200 MHz for CMOS output)

Preset pin-programmable frequency translation ratios cover

popular wireline and wireless frequency applications,

including xDSL, T1/E1, BITS, SONET, and Ethernet

Arbitrary frequency translation ratios via SPI port

On-chip VCO

Accepts a crystal resonator for holdover applications

Two single-ended (or one differential) reference input(s)

Two output clocks (independently programmable as LVDS,

LVPECL, or CMOS)

SPI-compatible, 3-wire programming interface

Single supply (3.3 V)

Very low power: <450 mW (under most conditions)

Small package size (5 mm × 5 mm)

Exceeds Telcordia GR-253-CORE jitter generation, transfer,

and tolerance specifications
