Texas Instruments · Clock And Data Recovery / Retiming · VQFN-48-EP(7x7)

SN75DP159RGZT from Texas Instruments, in a VQFN-48-EP(7x7). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SWAP/POL input 3-level input lane SWAP and polarity control pin; when I2C_EN/PIN = Low: H selects polarity swap (retimer only), L selects lane swap, No Connect is normal operation.
2 IN_D2p input Channel 2 differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
3 IN_D2n input Channel 2 differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
4 HPD_SRC output Hot plug detect output for source-side signaling.
5 IN_D1p input Channel 1 differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
6 IN_D1n input Channel 1 differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
7 GND power_in Ground connection.
8 IN_D0p input Channel 0 differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
9 IN_D0n input Channel 0 differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
10 I2C_EN/PIN input I2C enable/pin strap mode selection; H puts device into I2C control mode, L puts device into pin strap mode.
11 IN_CLKp input Clock differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
12 IN_CLKn input Clock differential input, AC-coupled TMDS or DisplayPort dual-mode physical level signal.
13 VCC power_in 3.3-V power supply.
14 VDD power_in 1.1-V power supply.
15 SCL_CTL input I2C clock signal; note that pin strapping takes priority when I2C_EN/PIN = Low.
16 SDA_CTL bidirectional I2C data signal; note that pin strapping takes priority when I2C_EN/PIN = Low.
17 NC unconnected No connect pin; blue pin names only in SNx5DP159 RGZ package.
18 CEC_EN output CEC control pin for dongle applications; blue pin names only in SNx5DP159 RGZ package.
19 GND power_in Ground connection.
20 PRE_SEL input 3-level de-emphasis pin strap when I2C_EN/PIN = Low; L = -2 dB, No Connect = 0 dB, H = reserved.
21 EQ_SEL/A0 input 3-level input receive equalization pin strap when I2C_EN/PIN = Low (L: 7.5 dB fixed; No Connect: adaptive; H: 14 dB fixed); address bit 0 when I2C_EN/PIN = High.
22 Vsadj input TMDS-compliant voltage swing control via nominal resistor to GND; recommend 6.4 kΩ for best transmit eye with minimum intra-pair skew.
23 VDD power_in 1.1-V power supply.
24 VDD power_in 1.1-V power supply.
25 OUT_CLKn output TMDS data clock differential output.
26 OUT_CLKp output TMDS data clock differential output.
27 HDMI_SEL/A1 input HDMI_SEL when I2C_EN/PIN = Low (H: DVI configured; L: HDMI configured with adaptor ID block readable); address bit 1 when I2C_EN/PIN = High; weak internal pull down.
28 OUT_D0n output TMDS data 0 differential output.
29 OUT_D0p output TMDS data 0 differential output.
30 GND power_in Ground connection.
31 OUT_D1n output TMDS data 1 differential output.
32 OUT_D1p output TMDS data 1 differential output.
33 HPD_SNK input Failsafe hot plug detect input from sink.
34 OUT_D2n output TMDS data 2 differential output.
35 OUT_D2p output TMDS data 2 differential output.
36 TX_TERM_CTL input 3-level transmit termination control when I2C_EN/PIN = Low; H: no termination, L: 75-150Ω, No Connect: auto-select based on data rate; blue pin names only in RGZ package.
37 VDD power_in 1.1-V power supply.
38 SCL_SNK bidirectional Failsafe sink side TMDS port bidirectional DDC data line.

41 GND power_in Ground connection.
42 OE input Operation enable/reset pin; L: power-down mode with outputs high impedance, H: normal operation; internal weak pullup (150-250 kΩ); must be low for minimum 100 µs before assertion.
43 VCC power_in 3.3-V power supply.
44 AUX_SRCn bidirectional Source side bidirectional DisplayPort auxiliary for I2C-over-AUX; blue pin names only in SNx5DP159 RGZ package.
