The AD9550 is a phase-locked loop (PLL) based clock translator designed to address the needs of wireline communication and base station applications. The device employs an integer-N PLL to accommodate the applicable frequency translation requirements. It accepts a single-ended input reference signal at the REF input. The AD9550 is pin programmable, providing a matrix of standard input/output frequency translations from a list of 15 possible input frequencies to a list of 51 possible output frequency pairs (OUT1 and OUT2). The AD9550 output is compatible with LVPECL, LVDS, or single-ended CMOS logic levels, although the AD9550 is implemented in a strictly CMOS process. The AD9550 operates over the extended industrial temperature range of −40°C to +85°C. APPLICATIONS * Cost effective replacement of high frequency VCXO, OCXO, and SAW resonators * Flexible frequency translation for wireline applications such as Ethernet, T1/E1, SONET/SDH, GPON, xDSL * Wireless infrastructure * Test and measurement (including handheld devices) * Converts preset standard input frequencies to standard output frequencies * Input frequencies from 8 kHz to 200 MHz * Output frequencies up to 810 MHz LVPECL and LVDS (200 MHz CMOS) * Preset pin-programmable frequency translation ratios * Single-ended CMOS reference input https://elecena.pl/product/17759183/integer-n-clock-translator-for-wireline-communications 2021-04-17 https://elecena.pl/product/17759183/integer-n-clock-translator-for-wireline-communications 2025-01-17
