The FX-104 is a SAW based frequency translator which is used to translate any input frequency such as 8 kHz, 1.544 MHz, 2.048 MHz, 19.440 MHz etc. to any specific frequency from 170 MHz to 777.6 MHz.
The FX-104 is a SAW‑based frequency translator that converts input frequencies ranging from 8 kHz to 170 MHz into output frequencies between 170 MHz and 777.6 MHz. It supports up to four different input frequencies per device and offers jitter generation and transfer performance compliant with GR‑253‑CORE specifications.
The data sheet lists electrical characteristics, mechanical dimensions, recommended reflow profiles, and handling precautions. It also includes a pin‑function table, typical application schematics, and ordering information for various voltage and frequency configurations.
| Output frequency range | 170 MHz – 777.6 MHz |
|---|---|

| Supply voltage (3.3 V option) | 3.15 V – 3.45 V |
| Supply current | 95 mA – 125 mA |
| Rise/Fall time (20 %‑80 %) | 250 ps – 400 ps |
| Output symmetry | 45 % – 58 % |
| Jitter generation (12 kHz‑20 MHz) | 0.23 ps – 1 ps |
| Jitter transfer (GR‑253‑CORE) | 0.1 dB |
| Operating temperature range | 0 °C – +70 °C (C) / –40 °C – +85 °C (F) |
| Package size | 25.4 mm × 20.32 mm × 6.35 mm |
Each FX-104 can be programmed to accept up to four different input frequencies.
The lock time is significantly less than one second for all supported input frequencies.
Yes; the FX-104 package is a drop‑in replacement for the FX‑102, with only the output enable/disable pin logic level differing.
