SA702 is a triple modulus low power ECL prescaler from Philips, used in synthesizer systems to achieve low phase lock time, broad operating range, high reference frequency and small frequency step sizes.
The SA702 is a triple‑modulus (divide by 64/65/72) low‑power ECL prescaler designed for RF synthesizer systems and battery‑operated devices such as cellular phones. It offers low current consumption, a wide operating frequency range up to 1.1 GHz, and is available in 8‑pin DIP and SO packages.
The document provides ordering codes, absolute maximum ratings, DC and AC electrical characteristics, timing diagrams, and test‑circuit information. It also includes graphs of minimum input power versus frequency and supply current versus voltage and temperature.
| Supply voltage range (Voc) | -0.3 to +7.0 V |
|---|---|
| Operating ambient temperature range (Ta) | -55 to +125 °C |
| Storage temperature range (Tste) | -65 to +125 °C |
| Minimum input slew rate (for fin < 50 MHz) | 32 V/µs |
The SA702 operates with a supply voltage (Voc) from –0.3 V to +7.0 V.
The 8‑pin DIP version uses order code SA702N 0404B, and the 8‑pin SO version uses SA702D 0174C.
