19 / 68 page  CX28331/CX28332/CX28333 1.0 Pin Description Single/Dual/Triple E3/DS3/STS-1 Line Interface Unit 1.1 Pin Assignments 100985A Conexant 1-9 46 —— REQH Ch1 Receive High EQ Gain Enable I The equalizer in the CX2833i has two gain settings. The higher gain setting is designed to optimally equalize a nominally-shaped (meets the pulse template), pulse-driven DS3 or STS-1 waveform that is driven through 0–900 feet of cable. Square-shaped pulses such as E3 or DS3-HIGH require less high-frequency gain and should use the low EQ gain setting. REQH = 1 high EQ gain (DS3/STS-1 modes) REQH = 0 low EQ gain (E3/DS3 Square Modes) — 70 70 REQH1 — 31 46 REQH2 Ch2 Receive High EQ Gain Enable —— 31 REQH3 Ch3 Receive High EQ Gain Enable I Power/Ground 12 —— TVDD TX power Ch1 P Power pins for transmit circuitry per channel (3.3 V). — 4 4 TVDD1 — 20 12 TVDD2 TX power Ch2 P —— 20 TVDD3 TX power Ch3 P 9 —— TVSS TX ground Ch1 P Ground pins for transmit circuitry per channel. — 1 1 TVSS1 — 17 9 TVSS2 TX ground Ch2 P —— 17 TVSS3 TX ground Ch3 P 13 —— RVDD RX power Ch1 P Power pins for receive circuitry per channel (3.3 V).
